Fix Assert: Wireframe XRay during Sculpting

In the situation that the viewport was set to solid/texture mode and
switch to wireframe and sculpt mode, an assert was triggered in
`workbench_cache_sculpt_populate`.

Cleanup: USD, removed unnecessary variable

No functional changes.

Cleanup: USD test, clarfied comment

Tests: Alembic, log entire command when `abcls` fails

This makes it easier to manually run the `abcls` when a test fails, aiding
inspection & fixing.

No function changes to actual Blender code.

Additional fix for T76426: Mantaflow Liquid - Gravity not respecting Time Scale from domain.

Removed time scale from another conversion factor. See also changes from 6400f54b4cc6.

Cleanup: USD, refactored export graph construction

The construction of the export graph is now split into a few steps:
- Construct a `HierarchyContext` object for the to-be-exported object.
- Determine the graph index, i.e. the export-parent and the duplicator.
- Update the `HierarchyContext` object for this graph index.

This allows the upcoming new Alembic exporter to override the location of
an object in the export graph, in order to support "flattened" exports.
Aside from that, this also simply makes the code cleaner.

No functional changes.

Cleanup: Alembic, moved axis conversion functions into their own files

The long-term goal is to move code out of `abc_util.{h,cc}` into either
files with better, more concrete names, or simply into the one file
where they are used.

No functional changes.

Fix T76484: Infinite event handling when loading with load_ui=False

When loading a file from the Python console with load_ui=False,
the event was never freed from the queue causing the command
to continuously be executed.
