This is part of T76372.
It adds the `blend_write`, `blend_read_data`, `blend_read_lib`
and `blend_read_expand` which correspond to the various
steps when reading and writing .blend files.
Having these callbacks allows us to decentralize the blenloader
code a lot more. This has the affect that code related to any
specific ID type is less scattered.

This adds an option to the Multires modifier to sculpt directly on the
base mesh while previewing the displacement of a higher subdivisions
level. What this does it considering Multires as a regular modifier
without exposing the grid displacement to sculpt mode.
This allows to see the propagation happening in real time, which enables
to use complex tools like Cloth or Pose in much higher resolutions and
without surface noise and artifacts.

This implements collisions in the solver of the cloth brush/filter. It

There are still some parameters (friction, distance to the surface...)
that can be exposed as properties in later patches.

When there is no color layer available,
BKE_sculpt_update_object_for_edit creates a new one and tags the mesh
with ID_RECLAC_GEOMETRY, so this layer is inmediatly available when the
tool starts. This also deletes the PBVH and when it is created again in
BKE_sculpt_update_object_after_eval, the pmap is not initialized, making
the tool crash.
This moves the color layer creation to a separate function outside
BKE_sculpt_update_object_for_edit, which now runs after the color
layer is available, so it won't need to update again and the pmap will
still be available when the tool is used.

This issue was produced by a hack in the sculpt mode code from 2.80
when the sculpt API for connectivity info was not available.
The smooth brush was the only brush that needed connectivity info,
so there were 3 different smooth functions with the connectivity
queries implemented for dyntopo, meshes and grids. The mesh version
of smoothing was checking the number of connected faces to a vertex
to mask the mesh boundaries, which was not covering all cases and
was hardcoded in the smooth function itself.
This patch removes all those legacy functions and unifies all
smooth functions into a single one using the new API and the
automasking system. In order to achieve this, there were needed
some extra changes:
- The smooth brush now does not automasks the boundaries by default,
so its default preset needs to be updated to enable automasking
- The mesh boundary info is extracted once and cached in a
bitmap, similar to the disconnected elements IDs. This makes
boundary detection work as expected in all cases, solving a lot
of known issues with the smooth brush. In multires, this info is
extracted and cached only at the base mesh level, so it is much
more memory efficient than the previous automasking system.
- In order to keep the brushes responsive as they were before,
the automasking system can now skip creating the cache when it
is not needed for the requested options. This means that for
high poly meshes and simple automasking options the brushes
won't lag on start.

This option allows posing meshes with different disconnected elements
using the Pose Brush.
This is achieved by doing the following:
- Creating an ID per vertex that stores the connected component of that vertex.
- By using those IDs, one fake topology connection is created per vertex to the nearest vertex in a different ID. The maximum distance to create that connection is determined by the "Max Element Distance" property. These fake connectivity neighbors are used in the Sculpt API functions iterators, so all the algorithms of the Pose Brush can run without modifications as if everything was part of the same mesh.
In order to make this work, the "Connected only" property of the Pose Brush needs to be disabled. This will add an extra performance cost to the Pose Brush and its preview. To achieve optimal results, max element distance should be as low as possible.

The report does not include any file, but probably that file is using the
settings for unified colors, which are currently not available in the UI,
so it always paints black. This enables unified colors and secondary
colors for sculpt vertex colors, so it should solve that issue.
Unified color does not make much sense now as the Paint tool is the only
one that has paint capabilities, but it will do in the future when
sculpt and paint at the same time is enabled and the paint capability is
added to more tools.

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)

- 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

The Layer brush was in Blender before 2.81, when the sculpt API was
introduced. It had a huge amount of bugs and glitches which made it
almost unusable for anything but the most trivial cases. Also, it needed
some hacks in the code just to support the persistent base.
The brush was completely rewritten using the Sculpt API. It fulfills the
same use case as the old one, but it has:
- All previous artifacts fixed
- Simpler code
- Persistent base now works with multires thanks to the sculpt API
- Small cursor widget to preview the layer height
- More controllable and smoother strength and deformation
- More correct masking support
- More predictable invert support. When using persistent base, the brush invert mode resets to layer height 0, instead of jumping from +1 to -1. The brush can still be inverted in the brush direction property.

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.

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.

- Multires support. The Face Sets and Visibility API needs to be implemented for Multires.

BKE_paint_init() should always ensure paint settings are initialized

The PBVH usually is rebuild after a topology change, so it does not make
sense to keep the previous dynamic mesh preview vertex list. This may
cause a crash is the number of vertices of the new mesh (and preview) is

When moving the brush, these segments are transformed using an IK solver and they are used to deform the mesh.
When pressing Ctrl, the brush controls the segments' roll rotation instead of using the IK solver. The brush falloff controls how much rotation is propagated from the first to the last segment in the chain.
