Merge branch 'master' into greasepencil-object

Fixup for cmake header cleanup

Issue introduced on f73a420e5aceb610bc38.

Merge branch 'asset-metadata' into asset-browser

Merge branch 'master' into asset-metadata

Geometry Nodes: Create the node group when adding a new Nodes modifier

Cleanup: Nodes Modifier header to its proper location

Operator to create asset catalogs (aka smart-filters)

A catalog at this stage is just a named item stored in a file's asset
repository meta-data.
With these changes one can create a named asset catalog that is written
to the file and can be read successfully.

XR: Improve error handling / messages

Originally thought that not terminating the session for certain "non-
fatal" errors (e.g. an incorrect action path) would make sense.
However, realized that error messages can pile up this way and it
is better for user feedback and debugging to always exit the session
when encountering an OpenXR-level error.

Geometry Nodes: do not reference custom data layers when copying mesh

We can't use that for now, because the original mesh might be freed
before the new copied mesh. When the original mesh is freed, the shared
layers will be freed as well.

This can probably be improved in the future, so that we can actually
share attribute arrays between meshes. An approach similar to how
geometries and components are shared should work as well.

Geometry Nodes: add comment mentioning that custom data might be shared

Geometry Nodes: refactor Geometry type

A geometry now contains zero or more geometry components.
A geometry component is a subclass off GeometryComponent.
Currently, there is a MeshComponent and PointCloudComponent.

A geometry contains at most one component of each type.
Individual components can be shared between multiple geometries
to avoid unnecessary copies. For that, each component has a user
count that determines when the component will be freed and whether
it is mutable.

Code working with geometries can either work with the components
directly, or use the utility functions on the geometry that cover the
most common operations.

In the future, additional component types can be added. For example,
we'll probably need components for curves and volumes.
Furthermore, something like an InstancesComponent can be added,
which contains points with attributes and references a geometry/object/collection
that is instanced on all the points.

Support storing asset repository data in files

Given that a repository can be built up from a single, or multiple
.blends, it's not clear where the repository data should live. It should
still be possible to easily share a .blend file to share assets,
including relevant meta-data that is not solely stored on the asset
level.
E.g. if you want to share a single pose library, that should be
doable by sharing a single .blend. So the .blend needs to have the pose
library meta-data, i.e. the name of the library and which poses belong
to it. The current design forsees that the Pose Library is implemented
as a "cataloge" (aka "smart-filter", to be determined). These should be
stored per asset category in the repository.

So this commit works towards the following design idea:
Each .blend file with assets can additionally store repository
meta-data. When reading a repository, we don't only read the asset
meta-data but also the repository meta-data in each .blend file. The
union over all the .blend files is the total repository meta-data the
asset browser can display.
That way each .blend file still is an isolated unit that doesn't
necessarily depend on the existence of other .blend files (or an index)
in the same repository.

This commit implements the storage framework of the repository meta-data.

I also added a temporary define to help spotting the related changes in
future.
