The `!BKE_previewimg_is_finished()` in `icon_preview_startjob_all_sizes()`
would fail.
Caused by 990bd9acf243ae. We have to be more picky about tagging previews as
unfinished after file read. But we also have to consider files stored in old
versions and set the unfinished tag as needed.
In D9722 we agreed on using `[home-directory]/Documents/Blender/Assets` for
the default asset library. I just forgot to do the change before committing.
(The default repository is just a named path, it's *not* a default library with
bundled assets.)
Previews would be flagged as unfinished when reading. Instead clear the flag
and always consider them finished upon reading. If we wouldn't do this, the
File Browser would keep running the preview updating to wait for the preview to
finish. It could be smarter and also check if there's actually a preview job
running.
Instead, I think it will just display an unfilled buffer for now. Up until
today we wouldn't even know if a stored preview is finished or not, so it would
always assume they are finished. We do the same now, but have the option to
make it smarter.
The Asset Browser will be a sub-editor of the File Browser. This prepares the
File Browser code for that.
**File-Lists**
* Support loading assets with metadata read from external files into the
file-list.
* New main based file-list type, for the "Current File" asset library.
* Refresh file-list when switching between browse modes or asset libraries.
* Support empty file-lists (asset library with no assets).
* Store file previews as icons, so scripts can reference them via icon-id. See
previous commit.
**Space Data**
* Introduce "browse mode" to differeniate between file and asset browsing.
* Add `FileAssetSelectParams` to `SpaceFile`, with `FileSelectParams` as base.
Makes sure data is separated between asset and file browsing when switching
between them. The active params can be obtained through
`ED_fileselect_get_active_params()`.
* `FileAssetSelectParams` stores the currently visible asset library ID.
* Introduce file history abstraction so file and asset browsing can keep a
separate history (previous and next directories).
**General**
* Option to only show asset data-blocks while file browsing (not exposed here).
* Add "active_file" context member, so scripts can get and display info about
the active file.
* Add "active_id" context member, so `ED_OT_lib_id_load_custom_preview` can set
a custom ID preview. (Only for "Current File" asset library)
* Expose some of `FileDirEntry` in RNA as (non-editable). That way scripts can
obtain name, preview icon and asset-data.

One of the core design aspects of the Asset Browser is that users can "mount"
custom asset libraries via the Preferences. Currently an asset library is just
a directory with one or more .blend files in it. We could easily support a
single .blend file as asset library as well (rather than a directory). It's
just disabled currently.
Note that in earlier designs, asset libraries were called repositories.
Idea is simple: In Preferences > File Paths, you can create custom libraries,
by setting a name and selecting a path. The name is ensured to be unique. If
the name or path are empty, the Asset Browser will not show it in the list of
available asset libraries.
The library path is not checked for validity, the Asset Browser will allow
selecting invalid libraries, but show a message instead of the file list, to
help the user understand what's going on.
Of course the actual Asset Browser UI is not part of this commit, it's in one
of the following ones.

This makes it possible to turn data-blocks into assets and back into normal

Asset metadata is what turns a regular data-block into an asset. It is a small
data-structure, but a key part of the technical design of the asset system.
The design foresees that asset data-blocks store an `ID.asset_data` pointer of
type `AssetMetaData`. This data **must not** have dependencies on other
data-blocks or data-block data, it must be an independent unit. That way we can
read asset-metadata from .blends without reading anything else from the file.
The Asset Browser will use this metadata (together with the data-block name,
preview and file path) to represent assets in the file list.
Includes:
* New `ID.asset_data` for asset metadata.
* Asset tags, description and custom properties.
* BKE code to manage asset meta-data and asset tags.
* Code to read asset data from files, without reading IDs.
* RNA for asset metadata (including tags)

This implements the design proposed in T83357.
The goal is to allow the geometry nodes modifier on mesh objects to
output instances and potentially other geometry types. Both problems
are tackled by allowing mesh objects to evaluate to a geometry set,
instead of just a single mesh id data block. The geometry set can
contain a mesh but also other data like instances and a point cloud.
I can't say that I'm sure that this commit won't introduce bugs. Mainly
the temporary object creation during rendering seems a bit brittle.
BUT, we can be reasonably sure that this commit will not introduce
regressions (at least not ones, that are hard to fix). This is because
the code has been written in a way that minimizes changes for existing
functionality.
Given that we intend to hide the point cloud object for the next release,
we won't even have to worry about temporary object creation for now.
An important part of the technical design is to make sure that
`ObjectRuntime->data_eval` contains the same data before and after this
patch. This helps to make sure, that existing code paths are impacted as
little as possible.
Instead of fully replacing `data_eval`, there is `geometry_set_eval`,
which contains all the geometry components an object evaluated to
(including the data referenced by `data_eval`).
For now, not much code has to be aware of `geometry_set_eval`. Mainly
the depsgraph object iterator and the instances system have to know
about it.

This is just for convenience since it allows animators to keyframe
outside of the strip's bounds by default. This was likely off by
default before since Syncing Length would undesirably shift the whole
animation after leaving tweak mode (fixed by {D7602}) and the animator
wasn't able to keyframe outside the strip bounds anyways
(fixed by {D7533}). Now it's better if the flag was on by default.
While the animator is still roughly developing their animation NLA-wise
they won't have to worry about strip bound keying failures. When they
are more certain of the strip bounds, they can disable the flag to
prevent affecting the rest of the NLA system.

This changes the way how the mattes are stored in the compositor node. This used to
be a single string what was decoded/encoded when needed. The new data structure
stores all entries in `CryptomatteEntry` and is converted to the old `matte_id`
property on the fly.
This is done for some future changes in the workflow where a more structured
approach leads to less confusing and easier to read code.
Object previews are really helpful for visual data-block selection, like asset
browsing. Having them be generative should also be quite handy and should work
well enough in many, if not most cases.
What this does is simple:
* Place the object (actually a deep copy of it, for thread safety) in a virtual
.blend into an empty scene/view-layer.
* Add a camera, point it towards the front of the object, assuming that means
pointing towards its +Y axis.
* Use "Camera Fit Frame to Selected" logic to put the object into frame.
* Create a threaded off-screen render.
Of course, such an automatic preview will not work in all situations. E.g. it
currently does a bad job capturing a single plane. We could add options for
more advanced automatic previews, but probably custom previews is more
important, which I committed already (812ea91842).

No automatic preview generation will ever be good enough to cover all cases
well. So custom preview images are a must for a preview driven data-block
selection - like for asset browsing.
The operator simply allows selecting an image file, which will then be read and
copied into the data-blocks preview (resized if necessary).
There's no UI for this currently and the operator won't be available in the
search menu yet. It will later once the Asset Browser UI is merged.

This is similar to c4a2067130130d, but applies to the general UI and is only
about single data-blocks. Here there was a similar problem: How can buttons
pass the data they represent to operators? We currently resort to ugly ad-hoc
solutions like `UI_context_active_but_get_tab_ID()`. So the operator would need
to know that it is executed on a tab button that represents a data-block.
A single button can now hand operators a data-block to operate on. The operator
can request it via the "id" context member (`CTX_data_pointer_get_type(C, "id",
&RNA_ID)` in C, `bpy.context.id` in .py).
In this commit, it is already set in the following places:
* Generic RNA button code sets it to the pointed to data-block, if the button
represents a data-block RNA pointer property. (I.e for general data-block
search buttons.)
* Data-block selectors (`templateID`) set it to the currently active data-block.
* The material slot UI-List sets it for each slot to the material it represents.
The button context menu code is modified so its operators use the context set
for the layout of its parent button (i.e. `layout.context_pointer_set()`).

The way the Outliner integrates operations on selected tree elements is known
to be quite problematic amongst developers. The context menu is generated in an
unusual way and doesn't use the normal operator system. Instead, changes are
applied via a recursive callback system. Things are quite ad-hoc, and the
callbacks often implement logic that should not be in the Outliner, but in
entirely different modules. Often these modules already contain the logic, but
as proper operators.
This commit is a step into a hopefully better direction that should allow us to
put actual operators into Outliner context menus. It starts solving the problem
of: How can the Outliner pass selected data to operators. It implements it for
data-blocks only, but other data could do it in the same way.
Idea is to keep doing what operators were initially designed to do: Operate on
context.
Operators can now query a "selected_ids" context member
(`CTX_data_selected_ids()` in C, `bpy.context.selected_ids` in .py). If an
Outliner is active, it will generate a list of selected data-blocks as a
response, via its `SpaceType.context` callback.
Any other editor could do the same.

** Removes apparently incorrect usage of `XDG_DOCUMENTS_DIR` on Unix systems -
this seems to be a config file variable, not an environment variable. Always
use `$HOME` instead, which this ended up using anyway.
** On Windows it doesn't attempt to use `%HOME%` anymore and gets the Documents

* Add `BKE_appdir_folder_documents()` to always get the user documents
directory on all platforms.
