OpenSubdiv: Refactor, move topology refiner factory to topology folder

OpenSubdiv: Refactor, move topology refiner to own folder

In the future factory will also be moved there.

OpenSubdiv: Refactor, move device specific code to own files

Also, move all device files to own folder.

Makes it so checks for device availability are done in a localized
place.

Cleanup: ID makelocal code: remove useless and confusing debug code.

Thing is, user code should not have the responsibility to check that
libquery is valid. Such checks are only source of confusion and errors
as nobody will think about finding and updating them in some obscure
specific area of the code...

Libquery: Refactor: add bmain to data passed to callback.

No reason to enforce defining own callback user data for something that
controlling has already available...

Fix T76997: bad handling of embedded IDs in partial append.

Code dealing with embedded data was pre-existing proper generic
handling of those by `BKE_library_foreach_ID_link()` - and was never
updated for scene's master collection it would seem...

Note that such fix/refactor is a bit risky at this point in the release
cycle, but on the other end previous situation was really broken. So
finger crossed. :|

Mesh: skip conversion from edit-mesh to mesh in edit-mode

This resolves a performance regression in 2.8x where every edit-mode
update performed an edit-mesh to mesh conversion.

Now the conversion will be lazily initialized if/when it's required.

New BKE_mesh_wrapper_* functions abstract over mesh data access.
Currently only edit-mesh and regular meshes are supported.
In the future sub-surface meshes may be supported too.

Fix autokeyframing masks not updating properly

Spotted while looking into T76872

Maniphest Tasks: T76872

Merge branch 'blender-v2.83-release'

Revert the changes for ccache and lld.

These were meant to be local changes & not pushed to the GSoC branch.
After discussion with the mentors, I'm adding this reverting commit.
Moreover, LLD for mach-o is not production ready & under development.
See [1] [2].

Now building the branch will not need any modifications.

Tests: correct the blender path for non-portable installations

Cleanup: unused variable warnings

GTest: BLI_ghash_performance_test was failing

Change the seed from 0 to 1, so BLI_ghash_performance_test doesn't
assert with duplicate keys.

Fix T76990: Crash shortest path select with 'face stepping' when no faces.

Note that this sometimes gives no solution when there is a mix of edges
with and without faces... But at leat this should be safe fix.

Task: Graph Flow Task Scheduling

Add TBB::flow graph scheduling to BLI_task.

Using flow graphs, a graph of nodes (tasks) and links can be defined.
Work can flow though the graph. During this process the execution of the nodes will be
scheduled among the available threads.

We are planning to use this to improve the threading in the draw manager.

The implemented API is still limited it only supports sequential flows. Joins and buffers
are not supported. We could eventually support them as part of an CPP API. These features
from uses compile time templates and are hard to make a clean C-API for this.
