VSE: make transform effect multithreaded

Multithreaded implementation can provide significant performance gain
on CPU's that can handle more parallel tasks.

On my 8 core system I got about 3.5x faster processing speed.

Fix T79594: Define rounding for armature edit props

Define `RNA_def_property_ui_range` for head and tail transform properties.
Step of 10 should match original behavior when tweaking value.

Fix T79757: Crash on prefetch when renaming strips

Original sequence lookup failed, becase name changed in another thread.
Fix is same as 0471349c90df - stop prefetching before changing content
of seqbase.

I have covered more cases, and added assert so it is more obvious that
issue is in lookup, and it shouldn't fail.

USD: Allow exporting of invisible objects

The fix for T75936 made it possible to export invisible objects to
Alembic. This commit applies the same approach to the USD exporter.

The USD and Alembic code is slightly different in terms of where in the
exported file the visibility attribute is stored. In USD the visibility
is used to prune the scene graph, and thus there are only two options:
"hidden" and "inherited". Setting the visiblity of a node in the scene
graph to "hidden" immediately hides all its children. To allow hidden
parents with visible children, the visibility is stored on the object
data (so the geometry/camera/lamp/etc) instead.

IO: Add test for iterating over invisible objects

Add a test that checks invisible objects are iterated over by the
`IO::AbstractHierarchyIterator` class, when a suitable depsgraph is given.

No functional changes.

Fix T75936: Alembic, allow exporting of invisible objects

Add a new depsgraph builder class that includes invisible objects and
use that in the Alembic exporter.

Alembic supports three options for visibility, "visible", "inherited",
and "hidden". This means that parents can be hidden and still have
visible children (contrary to USD, where invisibility is used to prune
an entire scene graph subtree). Because of this, the visibility is
stored on the transform node, as that represents the Object in Blender
and thus keeps the Alembic file as close to Blender's own structure as
possible.

Cleanup: IO, reduce code duplication in USD and Alembic exporters

Cleanup: Alembic, rename test in CMake for consistency

Rename test `alembic_tests` to `alembic_export_tests`, so that its name
is consistent with the Python file containing the tests,
`alembic_export_tests.py`.

Fix T79597: Crash with dyntopo after paint cursor refactor

The paint cursor now uses a single call to
SCULPT_cursor_geometry_info_update and the Sculpt API to update both the
radius and the SculptSession data, so random access needs to be
initialized for dyntopo before using API functions.
