This implements the Sculpt Mode API functions needed for Face Sets and
visibility management for PBVH_GRIDS. No major changes were needed in
the operators and the sculpt mode code. This implementation stores the
face sets in the base mesh, so faces created in higher subdivision
levels can't be modified individually. Also, we are not checking for
multiple face sets per vertex (that can be added in the future), so
relax tools don't work yet. The rest of the features (paint, undo,
visibility operators..) work as expected.

Clear is_identical_future before adding a next undo step, to avoid wrong
values for cases where we undo and then add a step with different changes
than what was previously the next step.

Required for collisions with moving rigid bodies. Otherwise the static optimization mode will be kept and the obstacles would be calculated only once at the beginning.
This is not dependent on having an armature as mentioned in T75111.
The collider simply has to be animated.

Might have happened when Apply Base is used in sculpt mode.
In practice this probably was fine, since the operator tags object
for update, so the pointers will be restored back to what they should
be.
Modify the view layer add operator (and underlying `BKE_view_layer_add`)
to allow for copying the current view layer, as well as adding a new one
but with all LayerCollections disabled by default (this is important for
heavy scenes where currently adding view layers can take a long time due
to enabling every collection by default).

This implements the Surface Smooth Brush as a mode inside the Smooth tool,
which uses the HC algorithm from "Improved Laplacian Smoothing of Noisy Surface Meshes".
Comparted to the regular smooth brush with laplacian smooth, this brush removes
the surface while preserving the volume of the object.
The smooth result can be controlled by tweaing the original shape preservation,
displacement and iteration count.
The same surface smooth operation is also available as a mesh filter.

Show control edges stores the control edges in the mesh which is
picked up by the draw manager. When applyng a subsurf (or multires) we
don't want that data present in the base mesh. Any rebuilding of the mesh
would overwrite the data anyway.
This patch introduces a new flag for applying modifiers
that can be checked to ignore storing display specific data in
the base mesh.

Caused by 18b693bdbd, due to lack of thread safety.
Beteween calling BKE_sequencer_cache_get_num_items and BKE_sequencer_cache_iterate
New items could be inserted in the cache.
BKE_sequencer_cache_iterate() now use 2 callbcack functions for initial setup
during which buffers with correct length can be initialized and finally iterating.
Additionally drawing of unselected items was fixed again introduced in 18b693bdbd.
T74662 is reporting quite different symptoms, than I get on my machine, so I am not
entirely sure this is complete fix.

Fixes an issue with secondary particles being out of sync with the main simulation. Cleaned up the secondary particle code in general too (making sure that all solver attributes - timestep, framelength, etc. - are set correctly).
It is not guaranteed that with Multires modifier existing there
will be CD_MDISPS and CD_GRID_PAINT_MASK custom data layers.
Fixes assert in the following scenario:
- With default cube, go to edit mode
- Add Multires modifier
- Remove the Multires modifier
Mpving utils from idcode to idtype proved to be somewhat painful for
some reasons, but now all looks good.
Had to add a fake/empty shell for the special snowflake too,
`ID_LINK_PLACEHOLDER/INDEX_ID_NULL`...
Is done by considering all base edges infinitely sharp.
In the future can become a different operator option to allow to mix
Catmull-Clark and simple subdivisions. For now just sticking to what
old good Blender versions were doing.
Fixes T74869: Simple subdivision type is not working as it should
The idea is following: only store information about edges which are
1. Communicated to the OpenSubdiv topology.
This rules out all loose edges, as they are not needed for the
propagation process.
2. Correspond to edge from the base mesh.
This avoids storing edges which are generated between inner face.
Those are not to have any sharpness to allow smooth propagation.
There is still possible to have memory peak in some obscure case when
mesh contains a lot of loose edges. It can be optimized further by
utilizing knowledge of the non-loose tags.
The title says it all actually. The test case is to get default cube,
set some edges to non-zero crease, add multires modifier and hit the
"Subdivide" button few times.
The memory footprint might be optimized by not storing information
about inner generated edges.
