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:

Editing of generic attributes on the original objects in edit modes is
still very limited. However, when applying a geometry nodes modifier
that generates new attributes. These attributes will show up in the
Attributes panel.
Currently, our exporters are not capable of exporting generic attributes.
Therefore, for the time being, a work around is to apply geometry nodes
and then convert a generic attribute to a task specific attribute like a
uv map, vertex group or vertex color layer. Once more parts of Blender
support generic attributes, this will become less important.
Currently, only meshes are supported by the operator. However, it would
be relatively easy to extend it to other geometry types.

This adds vertex creasing support for OpenSubDiv for modeling, rendering,
Alembic and USD I/O.
For modeling, vertex creasing follows the edge creasing implementation with an
operator accessible through the Vertex menu in Edit Mode, and some parameter in
the properties panel. The option in the Subsurf and Multires to use edge
creasing also affects vertex creasing.
The vertex crease data is stored as a CustomData layer, unlike edge creases
which for now are stored in `MEdge`, but will in the future also be moved to
a `CustomData` layer. See comments for details on the difference in behavior
for the `CD_CREASE` layer between egdes and vertices.
For Cycles this adds sockets on the Mesh node to hold data about which vertices
are creased (one socket for the indices, one for the weigths).
Viewport rendering of vertex creasing reuses the same color scheme as for edges
and creased vertices are drawn bigger than uncreased vertices.
For Alembic and USD, vertex crease support follows the edge crease
implementation, they are always read, but only exported if a `Subsurf` modifier
is present on the Mesh.

This commit moves the storage of `bDeformGroup` and the active index
to `Mesh`, `Lattice`, and `bGPdata` instead of `Object`. Utility
functions are added to allow easy access to the vertex groups given
an object or an ID.
As explained in T88951, the list of vertex group names is currently
stored separately per object, even though vertex group data is stored
on the geometry. This tends to complicate code and cause bugs,
especially as geometry is created procedurally and tied less closely
to an object.
The "Copy Vertex Groups to Linked" operator is removed, since they
are stored on the geometry anyway.
This patch leaves the object-level python API for vertex groups in
place. Creating a geometry-level RNA API can be a separate step;
the changes in this commit are invasive enough as it is.
Note that opening a file saved in 3.0 in an earlier version means
the vertex groups will not be available.

This adds a new Attributes panel in the mesh properties editor.
It shows a list of all the generic attributes on the mesh.
In the future, we want to show built-in and other attributes in the
list as well. Related technical design tasks: T88460, T89054.
There is also a new simple name collision check that warns the user
when there are multiple attributes with the same name. This can be
problematic when the attribute is supposed to be used in geometry
nodes or during rendering.

Previously the smooth shading of the voxel remesher was controlled by a
mesh property. With this change, the output will try to match the
current shading of the object. This only takes into consideration the
shading mode of the first polygon of the model, but it is probably what
most users expect as it works as intended with the shade smooth/flat
object mode options.

This bug was caused by making it so that non-embossed modifier icon
buttons could become an operator button and retain their red highlight
for disabled modifiers. The icon button needs emboss turned off, but
in earlier versions of Blender, `UI_EMBOSS_NONE` would be overridden
by animation or red alert states.
Instead of abusing "NONE" to mean "none unless there is animation or
red alert", this commit adds a new emboss flag for that situation,
`UI_EMBOSS_NONE_OR_STATUS`, which uses no emboss unless there is an
animation state, or another status. There are only a few situations
where this is necessary, so the change isn't too big.

Sculpt Vertex Colors is a painting system that runs inside sculpt mode, reusing all its tools and optimizations. This provides much better performance, easier to maintain code and more advanced features (new brush engine, filters, symmetry options, masks and face sets compatibility...). This is also the initial step for future features like vertex painting in Multires and brushes that can sculpt and paint at the same time.
This commit includes:
- SCULPT_UNDO_COLOR for undo support in sculpt mode
- SCULPT_UPDATE_COLOR and PBVH flags and rendering
- Sculpt Color API functions
- Sculpt capability for sculpt tools (only enabled in the Paint Brush for now)
- Rendering support in workbench (default to Sculpt Vertex Colors except in Vertex Paint)
- Conversion operator between MPropCol (Sculpt Vertex Colors) and MLoopCol (Vertex Paint)
- Remesher reprojection in the Voxel Remehser
- Paint Brush and Smear Brush with color smoothing in alt-smooth mode
- Parameters for the new brush engine (density, opacity, flow, wet paint mixing, tip scale) implemented in Sculpt Vertex Colors
- Color Filter
- Color picker (uses S shortcut, replaces smooth)

We use column or row headings here to bring more structure, and to give
the eye visual anchors which aid eye-scanning. The left-aligned
checkboxes likewise help with this. And we keep the adherence to the
center line, so the alignment matches up between the various buttons and
controls.
* Changes the property split percentage from 50/50% to 40/60%. This is
needed to give enough space for the checkboxes. But in most cases this
looks better anyway - see Transform panel. In some cases it simply
fills out the available space more efficently.
* Fix various hacks where we previously used manually defined splits.
When we did this, the alignment was never quite right, and the layout
code was a mess.
* Adds column headings to many places where a list of checkboxes all
share a common purpose or leading text.
* Add checkbox + value configurations various places where a checkbox
only serves to enable the value slider
* Removes most uses of grid flow layout. The grid flow layouts combine
poorly with column headings, and also they would mess alignment up
badly. The grid flow layouts also often made buttons and controls jump
around on the screen if you would just resize editors slightly,
causing visual confusion, making users lose their place. The logic for
at what time the list of items would re-flow was often flawed, jumping
to multiple columns too fast or too late - and frankly, the grid flow
layouts would often just look bad.

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.
