This introduces a variable to store a face set ID which is going to be
rendered white. When initializing a mesh or randomizing the colors, this
variable gets updated to always render a white face set. This way the
face set overlay can be enabled without adding colors to the mesh if
face sets are not in use. After creating the first face set, new colors
are generated randomly like usual.
The face set stored as default does not have any special meaning for
tools or brushes, it just affects the rendering color.

Face Sets are the new system to control the visibility state of the mesh in sculpt and paint modes. They are designed to work in modes where brushes are the primary way of interaction and they provide much more control when working with meshes with complex shapes and overlapping surfaces.
This initial commit includes:
- Sculpt Face Sets data structures and PBVH rendering.
- Face Set overlay and opacity controls.
- Sculpt Undo support.
- Remesher reprojection support. The visibility state of the mesh is also preserved when remeshing.
- Automasking and Mesh filter support.
- Mask expand operator mode to expand Face Sets (Shift + W) and flood fill areas by connectivity (press Ctrl while expanding).
- Sculpt Mode Face Sets and Visibility API.
- Sculpt Face Sets creation and visibility management operators.
- Operator to randomize the Face Sets colors.
- Draw Face Sets brush tool to create and edit the Face Sets. Drawing on the mesh creates a new Face Set. Pressing Ctrl before drawing modifies the Face Set under the brush at the beginning of the stroke.
- Updated keymap and menu to work with Face Sets from Sculpt Mode (H to toggle visibility, Alt + H to show all, Shit + H to hide).
- Pie menu on the W key with Face common Sets operations.
Know limitations:
- Multires support. The Face Sets and Visibility API needs to be implemented for Multires.

The coordinates should be read from the PBVH when using deform modifiers.
This is needed for the cloth brush to work with subdivisions, as it reads the
vertex coordinates using this function when building and updating the
constraints.

Currently, there its a function that sets manually the fully_hidden flag
of the nodes from the visibility operators in paint_hide.c. The undo
code was not updating the flag, so the visibility state of the nodes was
incorrect after preforming undo operations. This sometimes was drawing
fully hidden nodes with empty buffers, causing artifacts in the
geometry.
I added a function to mark nodes which visibility state changed (similar
as we are updating the mask flags and the nodes bounding boxes). This
way, the tools, operators and undo code don't have to update the
visibility flags, making everything much simpler to understand and
maintain.
I did not remove the flag update code from the current visibility
operators in this patch, but after reimplementing them (and all the new
ones) in the new visibility system, all visibility updates should be
done using this method and the BKE_pbvh_node_fully_hidden_set function
should be removed.

- Replace 'unsigned' used on it's own with 'uint'.

When a node was partially/fully hidden, this was causing the mask flags
to update incorrectly because it was not checking all vertices, so they
were assigned the fully_masked state and not updating in the transform
tool and mesh filter.

This solves performance issues on some computers where there is significant
threading overhead. Rather than doing the complicated work of optimizing our
own task scheduler, use TBB which appears to work well. The downside is that
we have another thread pool, but it is already there when using OpenVDB voxel
remesh.
For future releases we can switch to using TBB to replace our task scheduler
implementation entirely, and use the same thread pool for BLI_task, Cycles,
Mantaflow, etc.

This commit introduces flags to tag the PBVH nodes as fully masked or unmasked. This is used in do_brush_actions to filter fully masked nodes during a stroke. Other tools can also be updated to use this flags.
Sculpt updates now require a flag to update the mask or the vertex coordinates.

Also applies to some other sculpt tools like filter and mask expand.
The full update happens after the paint stroke is finished, so it does not
happen on view navigation, which would cause a delay.

This improves performance of some sculpt tools, particularly those that modify
many vertices like filter and mask tools, or use brushes with large radius.
For mask expand it can make updates up to 2x faster on heavy meshes, but for
most tools it's more on the order of 1-1.1x. There are bigger bottlenecks to
solve, like normal updates.

This is under the assumptions that each node has enough work to avoid
the threading overhead, while also having a possible variable amount of
work. For example most of the vertices being masked or outside of the
brush radius.
Improves performance by about 10% for tools like mesh filter on an
entire 3 million poly mesh, tested on a quad core.

This commit includes the new brush cursor, active vertex updates and the normal radius brush property for all sculpt brushes.
-The new brush cursor previews the real stroke radius over the mesh and the sampled sculpt normal.
-The active vertex is used in sculpt tools and brushes as a starting point for an operation, similar to a preselection. It is also mirrored following the enabled symmetry options to preview the stroke symmetry.
-The normal radius brush property limits the radius that is going to be used to sample the sculpt normal and area center. It controls how closely the cursor follows the surface and it improves the behavior of most brushes, making them suitable for hard surface sculpting.

The PBVHs raycast function calls `isect_ray_tri_epsilon_v3` with epsilon `0.1` which is inaccurate and may result in the problem presented in T65620.
The solution is to use `isect_ray_tri_watertight_v3` instead `isect_ray_tri_epsilon_v3`.
This can positively affect other areas as well.

It may be good to move the normals update out of the drawing code. But it was
already there for the non-multires sculpt cases, and does not have an obvious
place since we bypass the depsgraph and want to avoid the cost of updating the
normals multiple times when multiple events are handled before a redraw.

Workbench/Eevee now displays multiple multi-materials correctly.
Iterate over pbvh nodes when doing object iteration. This makes the
rendering process more streamlined and allow for using different materials.
This change will make possible to:
- Add culling pass of each pbvh leaf node. (speedup if zoomed on a small
area)
- Reduce number of lead node iteration.
- Reduce code complexity

Currently it is not possible to view the vertex colors of an object. To
optimize the workflow, workbench will need to support Vertex Colors.
The Vertex Colors is a new option in `shading->color_type`. When objects
do not have vertex color, the objects will be rendered with the
`V3D_SHADING_OBJECT_COLOR`.
In order to support vertex colors in workbench the current texture/solid
shading structure is migrated to a primary shaders and fallback shaders.

We already have different storages for cddata of verts, edges etc.,
'simply' do the same for the mask flags we use all around Blender code
to request some data, or limit some operation to some layers, etc.
Reason we need this is that some cddata types (like Normals) are
actually shared between verts/polys/loops, and we don’t want to generate
clnors everytime we request vnors!
As a side note, this also does final fix to T59338, which was the
trigger for this patch (need to request computed loop normals for
another mesh than evaluated one).

The multires sculpt drawing was a not working in smooth mode.
Also hidding was not supported by the wireframe overlay and flat shaded
faces.
Codewise it is cleaner and index buffers are only updated if the
smoothing changes.

This introduce the wireframe batches. Creating the indices buffer does
not seems to slow down the sculpt in my testing (but it is kind of hard to
