Cleanup: move AssetCatalogDefinitionFile functions together

No functional changes.

Asset Catalogs: read new on-disk catalogs before saving to disk

Before saving asset catalogs to disk, the to-be-overwritten file gets
inspected. Any new catalogs are loaded to memory.

- Changed catalog path: in-memory data wins
- Catalogs deleted on disk: they are recreated based on in-memory data
- Catalogs deleted in memory: deleted on disk as well
- New catalogs on disk: are loaded and thus survive the overwriting

Asset Catalog tests: initialise the tempdirs

Call `BKE_tempdir_init("")` to have non-empty tempdirs.

Cleanup: refactor asset catalog definition file loading

Change the API for loading asset catalog definition files, by moving the
file/line parsing code into the `AssetCatalogDefinitionFile` class.

This separates the parsing of these files from handling the parsed data.
The caller of the `parse_catalog_line()` function has to provide a callback
that stores the `AssetCatalog` in the desired place.

No functional changes.

Remove remaining C++ filesystem file & CMakeLists entries

Merge remote-tracking branch 'origin/master' into temp-asset-browser-catalogs

Remove ghc::filesystem files

Fix T91458: Displaying dope-sheet with sequencer keyframes crashes

Error in e6194e735791b42feb51e810a4910a41d999d3bf.

Use existing C-APIs for path and filesystem handling

The `ghc::filesystem` we wanted to use for a platform compatible
replacement of `std::filesystem` (see D12197) doesn't behave as we
expect or want to. We could probably find a solution, but it's not worth
the extra time. To move this forward, we can switch the asset catalogs
to use Blender's C functions for path and filesystem handling.

Cleanup ClangTidy warning.

Different parameter name in function declaration and implementation.

Make knife drawing anti aliased (Monkey work based on D11333)

Knife tool.

Make the drawing anti aliased and consistent by using
3D_POLYLINE/3D_POINT shaders, and making sure alpha
blending is on.

Cycles: merge of cycles-x branch, a major update to the renderer

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.

Fix script_load_keymap failure from c9d9bfa84ad5cb985e3feccffa702b2f3cc2adf8

Scanning the keymap hierarchy (used in the preferences),
caused the test to fail.

Don't attempt add fallback keymaps for dynamic keymap callbacks.

Cleanup: Silence unused variable warning

Merge branch 'master' into subdivision_work

Correct comment, spelling.

Remove todo comments.

Use proper enum type.

Don't put PatchMap into global namespace.

Use PIMPL idiom, put PatchMap in blender::opensubdiv namespace.
