Override layers are a standard feature of Alembic, where archives can override
data from other archives, provided that the hierarchies match.
This is useful for modifying a UV map, updating an animation, or even creating
some sort of LOD system where low resolution meshes are swapped by high resolution
versions.
It is possible to add UV maps and vertex colors using this system, however, they
will only appear in the spreadsheet editor when viewing evaluated data, as the UV
map and Vertex color UI only show data present on the original mesh.
Implementation wise, this adds a `CacheFileLayer` data structure to the `CacheFile`
DNA, as well as some operators and UI to present and manage the layers. For both
the Alembic importer and the Cycles procedural, the main change is creating an
archive from a list of filepaths, instead of a single one.
After importing the base file through the regular import operator, layers can be added
to or removed from the `CacheFile` via the UI list under the `Override Layers` panel
located in the Mesh Sequence Cache modifier. Layers can also be moved around or
hidden.

This add support for rendering of the point cloud object in Blender, as a native
geometry type in Cycles that is more memory and time efficient than instancing
sphere meshes. This can be useful for rendering sand, water splashes, particles,
motion graphics, etc.
Points are currently always rendered as spheres, with backface culling. More
shapes are likely to be added later, but this is the most important one and can
be customized with shaders.
For CPU rendering the Embree primitive is used, for GPU there is our own
intersection code. Motion blur is suppored. Volumes inside points are not
currently supported.
Implemented with help from:
* Kévin Dietrich: Alembic procedural integration
* Patrick Mourse: OptiX integration
* Josh Whelchel: update for cycles-x changes

I ran into this when adding new geometry nodes tests.
The issue was caused by 7168a4fa5c785c29483.

The test script did not work on windows
since it had some trouble importing the
api module on the blender side of things.
turning the file path to the module into
a raw string literal sidesteps the
backslash issue in the path.

WITH_OPENCOLORIO and WITH_COMPOSITOR are required to run the tests at all,
since they affect many tests.
WITH_OPENSUBDIV WITH_FREESTYLE, WITH_OPENVDB, WITH_OPENIMAGEDENOISE and
WITH_MOD_FLUID selectively disable some tests.
According to https://docs.python.org/3/library/os.html#os.rename,
`os.rename` has os-specific behavior, and will fail in case you attempt
to rename to an existing file on windows.
So using `os.replace` instead, which should be os-agnostic.
NOTE: Fact that temp test directory is not cleared after tests are
sucessfully ran does not sound great...
No need to report this, it just adds noise to the cmake config. The messages
that we need to keep are the ones about disabling tests when the test file or
idiff are missing.
As part of expected behavior this printed an exception,
making it seem as if there was an error in the test.
Now the exception is suppressed from the output, ensuring it matches
an the expected output.
This diff disables tests for Boolean, subdivision surface and volume
when GMP, Opensubdiv and Openvdb are not compiled respectively.
It also changes the existing file structure and adds sub-folders for
boolean and subdivison tests. The volume folder only has one test and
is as unchanged structure-wise.

This includes much improved GPU rendering performance, viewport interactivity,
new shadow catcher, revamped sampling settings, subsurface scattering anisotropy,
new GPU volume sampling, improved PMJ sampling pattern, and more.
Some features have also been removed or changed, breaking backwards compatibility.
Including the removal of the OpenCL backend, for which alternatives are under
development.

* Make "run" command (re-)run all tests, add "update" command to only
run queued and outdated tests equivalent to the old "run" command.
* Support specifying environment variables for revisions, to easily
compare multiple parameter values.
* Better sorting of revisions in graph.
