color attribute system.
This commit removes sculpt colors from experimental
status and unifies it with vertex colors. It
introduces the concept of "color attributes", which
are any attributes that represents colors. Color
attributes can be represented with byte or floating-point
numbers and can be stored in either vertices or
face corners.
Color attributes share a common namespace
(so you can no longer have a floating-point
sculpt color attribute and a byte vertex color
attribute with the same name).
Note: this commit does not include vertex paint mode,
which is a separate patch, see:

This is part of the project of converting `MVert` into `float3`.
(more details in T93602), The pbvh update flag is removed and
replaced with a bitmap stored in the PBVH structure. This
patch is similar to D13878. This is mainly setup for an eventual
performance improvement by removing the extra data from
mesh vertices, but if it's consistent with testing in the other patch
doing the same thing for another "temp tag", then it may actually
increase the speed of sculpt code slightly, since less memory needs
to be loaded when checking/changing the flags.

By argument naming and convention this is the intended argument order.

Expand is not expected to update the visibility state of the PBVH, only
the Face Sets IDs. If visibility updates are made accidentally, PBVH
rendering breaks.
In order for this to work properly, the following fixes are needed:
- Expand should always check for active component before attempting to
modify a Face Set ID
- Expand should always check the visibility state on original_face_sets, as
it is the array that contains the visiblilty state that corresponds with the
current state used for PBVH rendering. This implies that after any modification
done by Expand, the visibility state of ss->face_sets and
expand_cache->original_face_sets should match (like in any other tool that
does not modify visibility).
- Expand should never modify the Face Set ID of a poly that is hidden in
expand_cache->original_face_sets.
- When deleting an ID, hidden Face Sets should be skipped when picking IDs for
content filling. This avoids introducing hidden IDs back into the visible
geometry even after updating its visibility state.

When checking if the mesh has only one Face Set only the current active
component for expand needs to be checked. Otherwhise other components
that won't be modified by Expand that contain other IDs will be taken
into account, making the Face Set deletion go into an infinite loop.

Expand is a new operator for Sculpt Mode which is intended to be the main
tool for masking, Face Set editing, interacting with the filters and pattern
creation.
The fundamentals of the tool are similar to the previous sculpt.mask_expand
operator. It shares the same default shortcuts and functionality, making
the previous operator obsolete.
The shortcuts to execute the operator are:
- Shift + A: Expand mask
- Shift + Alt + A: Expand mask by normals
- Shift + W: Expand Face Set
- Shift + Alt + W: Resize current Face Set
The main changes compared to the previous sculpt.mask_expand operator are:
- Modal keymap, all operator options can be changed in real time while the
operator is running.
- Supports creating Mask, Face Sets and Sculpt Vertex Colors.
- Much better code, new features can be easily integrated.
Limitations:
- All Mask operations are supported for Sculpt Vertex colors, but not exposed
by default as their support is still experimental.
- Dyntopo does not support any Face Set or Sculpt Vertex Colors. functionality
(they are not implemented in general for Dyntopo).
- Multires does not support any feature related to geodesic distances.
- Multires does not support vertex colors.
- Multires does not support recursions.
- In Multires, Face Sets snaping does not initialize all current enabled Face
Sets when toggling snapping.
- In Multires, Face Sets are created at base mesh level (works by this by
design, like any other tool).
- Unlike the previous mask_expand operator, this one does not blur the mask
by default after finishing Expand as that does not fit the new design.
The mask can still be blurred by using the mask filter manually.
