BMesh: multi-thread face tessellation

Use BM_iter_parallel for face tessellation, this gives around
6.5x speedup for BM_mesh_calc_tessellation on high poly meshes in my
tests, although exact speedup depends on available cores.

BLI_task: add TLS support to BLI_task_parallel_mempool

Support thread local storage for BLI_task_parallel_mempool,
as well as support for the reduce and free callbacks.

mempool_iter_threadsafe_* functions have been moved into a private
header thats only shared between task_iterator.c and BLI_mempool.c
so the TLS can be made part of the iterator array without having to
rely on passing in struct offsets.

Add test task.MempoolIterTLS that ensures reduce and free
are working as expected.

GPencil: Add custom normal entry to bGPDspoint.

Also modified existing utility functions to take
care of the new surface normal interpolation and so on.

Fix assigning material to linked object being forbidden in BKE.

While this should not be allowed in general, there are some cases
(library overrides at least) where supporting this is mandatory.

Further more, comment stating that this could crash is from 2011, could
not reproduce any issue with current code. Commit comment was referring
to undo/redo, but in use cases here those should not affect things.

Note that in general, such relatively high-level checks should be
handled by high-level, close to user code (like in ED area e.g.), not in
low-level BKE code anyway.

Cleanup: Removed unused definition.

T88352: Use threaded ibo.tris extraction for single material meshes.

This patch adds a specific extraction method when the mesh has only
one material. This method is multi-threaded.

There is a trade-off in this patch as the ibo isn't compressed (it adds
restart indexes for hidden faces). So it depends if threading is faster
than the additional GPU buffer upload.

# Subdivided cube
I used a cube subdivided 7 times, modifiers applied. that gives around 400000 faces.

The test is selecting some vertices and move them. During this test the next buffers are updated on each frame:
* vbo.pos_nor
* vbo.lnor
* vbo.edit_data
* ibo.tris
* ibo.points

UI: Add the option to not display some socket labels

This commit adds a flag to disable displaying some socket labels which
just redundant eye sores. We still want to have a label, because that
information can potentially be accessed elsewhere in the UI.

The flag is used in a few geometry nodes.

GPencil: Second test of thin lines

Fix T88885: Circle select deselects first selections after moving cursor

`is_active_prev` is always set after the first operation.
But this was not the case with `wait_for_input` `false`.

Tests: temporarily increase threshold for OpenImageDenoise test

Until all platforms have the same version, this helps the tests pass.

ReadFile stats: Add more data to new BlendReadFileReport structure.

Fix T88998: GPencil not projecting to the most front surface

It was projecting from the stroke position.

The behavior has changed in {rB5400be9ffee2}.

Draw Cache: use threading for Mesh extract lines

This is an optimization, but the difference is still not that
significant as some extractions are still done in single thread.
