Adds a test to validate the import of Mesh attributes for USD.
It reuses the recently added export attribute test file to generate the
USD file to load.
The test validates the current behavior in `main`. Missing data and bugs
are noted in comments and can be addressed afterwards.

Implement the design discussed in #120384.
This adds two parameters. One for changing the approximation
method, and another to use the thickness from shadow map.
We pack the former in the gbuffer by dividing the 16bits
used for thickness by two and use one bit to store the
method.
The thickness from shadow map is now decoupled from the
light evaluation shader. This makes it more performant and
compatible with ray-tracing. This commit also uses the
same biases as shadow mapping to avoid aliasing artifacts
(fix#119339).
This refactors the light evaluation quite a bit to
remove unused bits bits and make the whole transmission
light evaluation without too much complexity.

Add an RNA enum property `AnimData.animation_binding` that lists all the
bindings available in `AnimData.animation`.
The list of bindings is filtered to only contain the bindings suitable
for the animated ID. This prevents assigning a 'camera' binding to a
mesh.
Un-assigning is done via an operator, represented as an 'X' button in
the interface.
The enum property contains up to two special items:
- "New" to create a new binding for the ID.
- "(none/legacy)" to indicate that this ID doesn't have a binding
assigned. This one is conditional, and only appears when it is
necessary.
These two special items are experimental, and mostly exist because we're
still evaluating things and building a better UI. It is intended that
the binding selector will become as close to the ID selector as
possible.

Note that this PR also contains #121268 as it builds up from that one, and I didn't want to wait with testing on the buildbot until that one lands.

Refuse to set the RNA property `AnimData.animation_binding_handle` when
`AnimData.animation` is nil.
When in a hypothetical future `AnimData.animation` would be set, the
binding handle would be ignored anyway, as it's only meaningful within
the context of a known animation. Refusing to set the binding handle in
cases where it is known to be meaningless may help to find bugs in
Python scripts.

Add an optional keyword argument `keytype` to the
`rna_struct.keyframe_insert()` function.
This makes it possible to set the new key's type. The code for this was
almost all in place, the only thing that was missing was the RNA
wrapper, which is what this commit adds.
Example: `bpy.context.object.keyframe_insert("location",
keytype='JITTER')`
There is no backward compatibility issue here, because the argument is
optional and defaults to the previously hardcoded value of `KEYFRAME`.

Expand the `AnimData` struct with an `Animation *` + an
`binding_stable_index` field, and properly handle those relations.
This also adds functionality for actually pointing animated IDs to
`Animation` data-blocks, and automatically hooking up the relevant
`Binding`.
The Depsgraph code is extended to take these new relations into account,
but doesn't trigger any animation evaluation yet.
For more info, see #113594.

Add code (including RNA wrappers) for:
- Creating, removing, and accessing `Animation` data-blocks.
- Creating and removing layers, strips, and bindings on those `Animation`
data-blocks.
- Accessing those via RNA.
Note that this does not include assignment to any animated data-block,
so it is of limited practical use.
For more info, see #113594.

The curve variations were used during development of the GeometrySet
changes.
The lights and point instancer coverage would have helped uncover bugs
earlier. Bugs that eventually had to be fixed in 4.1. Better late than
never.
The one downside is that the light tests is actually a round-trip test,
which is normally fine to do, except it technically does an export
during the import test.

Often when the reference linked data is significantly modified, a lot of
'ghost' linked data remain referenced by liboverrides, even after
resync. This is due to the fact that missing data is ignored (skipped)
during resync process, to avoid potential destruction of data in case
the linked data is actually missing.
However, after all resync has been done, we can consider that missing
linked references and their liboverrides can be safely deleted, if the
later are not user-edited or hierarchy roots.
Nested panels are not supported currently, and this parameter serves no
actual purposes. Only the root panel supports adding child panels and it
is not user-accessible (adding the root panel is done using a nullptr
for the parent).

This change makes it so build system and update utilities for Blender builds
are using pre-compiled libraries and other resources attached as Git modules
instead of using checkout of SVN repositories in the parent folder.
The directory layout:
```
* release/datafiles/
* assets/ -> blender-assets.git
* publish/
* ...
* README.txt
* lib/
* darwin_x64/ -> lib-darwin_x64.git
* darwin_arm64/ -> lib-darwin_arm64.git
* linux_x64/ -> lib-linux_x64.git
* windows_x64/ -> lib-windows_x64.git
* tests/
* data/ -> blender-test-data.git
```
The changes about configuring the actual Git sub-modules are not included
into this patch, as those require repository to actually exist before it
can be used.
The assets submodule is enabled by default, and the rest of them are
disabled. This means that if someone runs `git submodule update --init`
they will not get heavy libraries. The platform-specific and tests
related submodules are enabled when using `make update` or `make test`.
All the submodules are tracked: this means that when new commits are
done to the submodule, the blender.git repository is to be updated to
point them to the new hash. This causes some extra manual work, but it
allows to more easily update Blender and its dependencies to known good
state when performing operations like bisect.

The Realtime Compositor uses the CPU compositor. That's because the enum
identifier of the Realtime Compositor changed to GPU, so update the test
script accordingly.
This improves the volume probe resolution and
dimensions to envelope most test scenes.
This doesn't increase the baking time
that much as most of the baking time is
spent compiling shaders.
- Avoid using `except: pass` so broken script don't go
undetected.
- Increase resolution of volumes
- Increase motion blur step resolution
- Fix setting on all scenes
