The storage of IDProperty UI data (min, max, default value, etc) is
quite complicated. For every property, retrieving a single one of these
values involves three string lookups. First for the "_RNA_UI" group
property, then another for a group with the property's name, then for
the data value name. Not only is this inefficient, it's hard to reason
about, unintuitive, and not at all self-explanatory.
This commit replaces that system with a UI data struct directly in the
IDProperty. If it's not used, the only cost is of a NULL pointer. Beyond
storing the description, name, and RNA subtype, derived structs are used
to store type specific UI data like min and max.
Note that this means that addons using (abusing) the `_RNA_UI` custom
property will have to be changed. A few places in the addons repository
will be changed after this commit with D9919.
**Before**
Before, first the _RNA_UI subgroup is retrieved the _RNA_UI group,
then the subgroup for the original property, then specific UI data
is accessed like any other IDProperty.
```
prop = rna_idprop_ui_prop_get(idproperties_owner, "prop_name", create=True)
prop["min"] = 1.0
```
**After**
After, the `id_properties_ui` function for RNA structs returns a python
object specifically for managing an IDProperty's UI data.
```
ui_data = idproperties_owner.id_properties_ui("prop_name")
ui_data.update(min=1.0)
```
In addition to `update`, there are now other functions:
- `as_dict`: Returns a dictionary of the property's UI data.
- `clear`: Removes the property's UI data.
- `update_from`: Copy UI data between properties,
even if they have different owners.

If there were lots of selected objects without an existing rigid body,
we would add rigid bodies to them one by one.
This would be slow in python, now we instead do this as a batch
operation in C.
On my (Intel) MacBook it used to take 60 seconds and with this change it
takes about 0.3 seconds.

`split_multicam` used split operator, where if more strips than
multicam were selected, all would be split, which is undesirable.
Add `Sequence.split()` RNA API function. to split individual strips.
Function accepts `frame` and `split_method arguments`. Returns right
strip after splitting.
In case when strip being split have effects, these will be split too, so
no invalid state should be created.
Selection is not handled, this is by design up to user.

Add operator 'Open Blend File' to the Asset Browser. This operator:
- starts a new Blender process,
- opens the blend file containing the asset,
- monitors the new Blender process, and when it stops,
- reloads the assets to show any changes made.
This adds a viewer node similar to the one in the compositor.
The icon in the headers of nodes is removed because it served
the same purpose and is not necessary anymore.
Node outputs can be connected to the active viewer using
ctrl+shift+LMB, just like in the compositor. Right now this collides
with the shortcut used in the node wrangler addon, which will
be changed separately.
As of now, the viewed geometry is only visible in the spreadsheet.
Viewport visualization will be added separately.
There are a couple of benefits of using a viewer node compared
to the old approach with the icon in the node header:
* Better support for nodes that have more than one geometry output.
* It's more consistent with the compositor.
* If attributes become decoupled from geometry in the future,
the viewer can have a separate input for the attribute to visualize.
* The viewer node could potentially have visualization settings.
* Allows to keep "visualization points" around by having multiple
viewer nodes.
* Less visual clutter in node headers.

The same code existed in 2.82 and earlier so this should be safe. Removing the
custom implementation of shutil.copytree in f34d5d9 did not correctly add back
the option to copy symlinks.
'Preferences' is the term used elsewhere in Blender so this commit makes
the option more consistent.
In the future, the "default" target could be changed to something more
descriptive.
Partial fix for T81751 which exposes multiple playback performance
issues. Previously the cache was limited to 30 frames, without a way to
increase the cache for smooth playback with files that are slow to load.
Now the animation plays back smoothly once loaded into cache.
The cache limit from the system preference is used
when the player is launched from Blender.
A new player argument `-c <cache_limit>` was added to support this.
This changes the following items:
- package name is now `blender-3.0.0-git.09eb04c0a865-windows64`
rather than `blender-3.00.0-git.09eb04c0a865-windows64`
- Fix version resource for blender.exe not building
- Data directories are now `3.0\...` rather than `3.00\....`
- User prefs are now in:
`c:\Users\users\AppData\Roaming\Blender Foundation\Blender\3.0\`
rather than:
`c:\Users\users\AppData\Roaming\Blender Foundation\Blender\3.00\`
- Updating startup & preferences from previous release
has a special exception for 3.0 to check for 3.93 and older.

This introduces a context path to the spreadsheet editor, which contains
information about what data is shown in the spreadsheet. The context
path (breadcrumbs) can reference a specific node in a node group
hierarchy. During object evaluation, the geometry nodes modifier checks
what data is currently requested by visible spreadsheets and stores
the corresponding geometry sets separately for later access.
The context path can be updated by the user explicitely, by clicking
on the new icon in the header of nodes. Under some circumstances,
the context path is updated automatically based on Blender's context.
This patch also consolidates the "Node" and "Final" object evaluation
mode to just "Evaluated". Based on the current context path, either
the final geometry set of an object will be displayed, or the data at
a specific node.
The new preview icon in geometry nodes now behaves more like
a toggle. It can be clicked again to clear the context path in an
open spreadsheet editor.
Previously, only an object could be pinned in the spreadsheet editor.
Now it is possible to pin the entire context path. That allows two
different spreadsheets to display geometry data from two different
nodes.
The breadcrumbs in the spreadsheet header can be collapsed by
clicking on the arrow icons. It's not ideal but works well for now.
This might be changed again, if we get a data set region on the left.

Use utility functions to decompose data paths and resolve the
RNA property from a data-path.
Replaces in-line string manipulation and RNA access.
This allows more complex data paths to be used, where previously string
literals in a data path could break the simple data-path handling logic.
Generic context operators now look-up the RNA properties to extract
their description (when it's available).
Add `bl_rna_utils.data_path.property_definition_from_data_path()`
to handle the details of accessing the RNA property definition.
Warnings in tooltips were using inconsistent formatting, some in
parantheses, some not, some in caps, others not, some on new lines,

This implements the MVP for the new spreadsheet editor (T85879). The functionality
is still very limited, but it proved to be useful already. A more complete picture
of where we want to go with the new editor can be found in T86279.
Supported features:
* Show point attributes of evaluated meshes (no original data, no other domains,
no other geometry types, yet). Since only meshes are supported right now, the
output of the Point Distribute is not shown, because it is a point cloud.
* Only show data for selected vertices when the mesh is in edit mode.
Different parts of Blender keep track of selection state and original-indices with
varying degrees of success. Therefore, when the selected-only filter is used, the
result might be a bit confusing when using some modifiers or nodes. This will
be improved in the future.
* All data is readonly. Since only evaluated data is displayed currently, it has to
be readonly. However, this is not an inherent limitation of the spreadsheet editor.
In the future editable data will be displayed as well.
Some boilerplate code for the new editor has been committed before in
rB9cb5f0a2282a7a84f7f8636b43a32bdc04b51cd5.
It would be good to let the spreadsheet editor mature for a couple of weeks as part
of the geometry nodes project. Then other modules are invited to show their own data
in the new editor!

In general, I could not find a reason executing from the python console
should not do an Undo push. Running a script from the Text Editor does
this as well and this seems generally useful.
Without an Undo push, one can easily run into situations were IDs have
been added or removed and undo on would then cause trouble (e.g. first
selection then bpy.ops.object.duplicate() -- this crashed as reported in
T86293 -- duplicate does not get its own undo push because it is not the
last op in the list, wm->op_undo_depth is not zero). This has changed
with the Undo refactor, so in essence the root cause is the same as
T77557, Legacy Undo does not suffer from the crash (but misses
the generally useful undo push from the console still)
Now add Undo to CONSOLE_OT_execute bl_options ('UNDO_GROUPED' seems more
appropriate than plain 'UNDO' since pasting multiple lines of code will
call CONSOLE_OT_execute multiple times in a row).

- Enable Python's postponed annotations for Blender's RNA classes
types registered on startup.
- Using postponed annotations has implications for how they are defined,
since they must evaluate in the modules name-space instead of the
classes name-space. See changes to annotations in `release/scripts`.
- Use `from __future__ import annotations` at the top of the module
to ensure the script will run with Python 3.10.
- Old logic is kept since it could be used if PEP-649 is supported.
