Avoiding creating empty components can be a hassle for code that
interacts with a geometry set. One easy way to do that was calling
the functions that retrieved mutable access to geometry data directly,
like get_mesh_for_write. This commit makes it so that sort of direct
function does not create an empty component if there is no data.
Another way to create an empty component was calling the replace_*
methods with a null pointer. It's more convenient to have a nice API
that handles those cases without creating an empty component.
It's still convenient that the regular get_component_for_write adds
the component if it doesn't exist, because that's often a nice way to
add data to the geometry set.

This commit adds a fields version of the mesh to curve node, with a
field for the input selection. In order to reduce code duplication,
it adds the mesh to curve conversion to the new geometry module
and calls that implementation from both places.

The Alembic/CacheFile modifier supports Cycles procedurals when Cycles
is configured to use experimental features; the check for this would
segfault on builds with `WITH_CYCLES=OFF`. This is now fixed by adding
an extra NULL check.
This changes the edge split node to have a selection input, which is
more aligned with the other design changes. This loses the ability to
split edges based on an angle, but the edge angle can be added as a
field input node in the future, which will make for a much more
flexible system.

Adds a node that can rotate each of a geometry's instances in global
(to the modifier object) or local space (of each point) by a specified
angle around a pivot point.
In the future, separating the local-global choice for the pivot and the
rotation might be useful. However, for now the node is kept simple.

Adds a node that can scale a geometry's instances. With "Local" turned
on, the instance is scaled individually from the center point input,
while when local space is turned off, it's more like the transform
node, except it scales outward from the center point instead of only
from the origin.

Adds a node that can translate instances in the transform space of
the modifier object, or the local space of their original transform.
One reason to have a special node for instances is that they always
have the existing transform, unlike mesh or point cloud points.

When assigning a new catalog ID to an asset, also refresh the "catalog
simple name". This "simple name" is stored on the asset metadata next to
the catalog UUID, to allow some emergency data recovery when the catalog
definition file is somehow lost.
Since `AssetCatalogPath` isn't default constructible (unlike the
previous `CatalogPath`, alias `std::string`), `AssetCatalog` isn't
default constructible either. But its default constructor is declared
with `= default` which Apple Clang was warning about.

Ensure that catalog operations create an undo snapshot, and show
undo/redo operators in the asset browser.
A hidden operator `ASSET_OT_catalog_undo_push` is also added such that
add-ons can also set undo snapshots if they need.
Rename `bke::AssetCatalogService::store_undo_snapshot` to `undo_push`.
This makes the function named the same way as the global Blender "undo
push" function.
No functional changes.
Add an undo stack for catalog edits. This only implements the backend,
no operators or UI yet.
A bunch of `this->xxx` has been replaced by `catalog_collection_->xxx`.
Things are getting a bit long, and the class is turning into a god

Recursively delete asset catalogs with `AssetCatalogService:prune_...`
functions. This deletes the catalog and all of its children.
The old `delete_catalog` function has been renamed to
`delete_catalog_by_id()`, and is now a lower-level function (no deletion
of children, no rebuilding of the tree). The `prune_catalogs_by_path()`
and `prune_catalogs_by_id()` do delete children and do rebuild the
catalog tree.

Simplify the testing code that verifies the asset catalog tree. It now
prints clearer error messages when things go wrong, and it gets simpler

just counts the number of separators in the expected path).

This commit implements T91780, adding nodes to get and set builtin
attributes. Individual set nodes are used so that the values can be
exposed for direct editing, which is useful for attributes like shade
smooth and spline resolution. Individual input nodes are used to allow
reusing nodes for multiple components, and to allow grouping multiple
outputs conceptually in the same node in the future.
Input Nodes
- Radius
- Curve Tilt
- Curve Handle Positions
- Is Shade Smooth
- Spline Resolution
- Is Spline Cyclic
'Set' Nodes
- Curve Radius
- Point Radius
- Curve Tilt
- Curve Handle Positions
- Is Shade Smooth
- Spline Resolution
- Is Spline Cyclic
Using hardcoded categories is necessary to add separators to the node
menu.

Delete Geometry:
This adds a copy of the old node in the legacy folder and updates the
node to work with fields. The invert option is removed, because it is
something that should be very easy with fields, and to be consistent
with other nodes which have a selection. There is also a dropdown to
select the domain, because the domain can't be determined from the
field input. When the domain does not belong on any of the components
an info message is displayed.
Separate Geometry:
A more general version of the old Point Separate node. The "inverted"
output is the same as using the delete geometry node.

This commit introduces the Align Euler to Vector function node which
rotates to a body into a given direction. The node replaces the legacy
"Align Rotation to Vector" node, which only worked on an attribute
named `rotation` internally. The "Euler" in the name is meant to make
it clearer that the rotation isn't interchangeable with a regular
vector.

This bug was introduced in D12190 because the list of types that support materials did not include GPencil and this caused all materials to be removed after they were created during conversion.
Moved function definitions around so that all members of a class are

Change the rules for determining where to save a new catalog definition
file (CDF).
Old situation (T91681): if a `blender_assets.cats.txt` file already
exists in the same directory as the blend file, write to that. If not,
see if the blend file is contained in an asset library, and write to its
top-level CDF.
The new situation swaps the rules: first see if the blend file is
contained in an asset library, and if so write to its top-level CDF. If
not, write a CDF next to the blend file.
As before, any pre-existing CDF is not just bluntly overwritten, but
merged with the in-memory catalogs.
Liboverride references need a special handling during append, since
those pointers should never be made local, nor reampped to newly
localized data. And liboverride references should never be directly made
local either, to ensure their liboverride usages remain pointing to
linked data and not local one.
Issue was reported by the studio, and also probably as part of T91892.
This didn't belong on blenlib since it uses DNA data types
and included a bad-level call to BKE_curve.h.
It also meant linking in blenlib would depend on the freetype library,
noticeable for thumbnail extraction (see D6408).
