Multires uses the data of the Face Sets stored in the base mesh to
manage the grid's visibility, so these pointers can no longer be set to
NULL when editing Multires objects as they are requried for some operations.

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.

The `BKE_animsys.h` and `anim_sys.c` files already had a an "AnimData
API" section. The code in that section has now been split off, and
placed into `BKE_anim_data.h` and `anim_data.c`.
All files that used to include `BKE_animsys.h` have been adjusted to
only include the animation headers they need (sometimes none).

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

Steps to reproduce were:
* Add new (empty) scene
* Add some mesh object
* Change to texture paint mode
While it can be argued that we should already init the settings when
creating a new scene (so that the texture tab can show up),
BKE_paint_init() should always ensure paint settings are initialized
either way.
Related to T73611.
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
larger previous one. Now the list is deleted with the PBVH and a new one
will be generated using the new mesh when the cursor is updated.

This commits introduces the pose_ik_segments brush property in the Pose Brush. When increasing the IK segments count, the brush generates more segments and weights associations following the topology of the mesh. 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.

Issue likely caused by 8b31f6fb21.
With this, initializing the toolsystem (e.g. for a new workspace-scene
combination) would skip the entire create->initialize routine for
image/texture painting settings. Reason being that these are not
allocated, unlike other paint settings. So while correctly skipping the
create part, it also skipped the initialization, which was still needed.
This does further changes in related code to avoid NULL pointer
accesses.
Extend options are currently stored per curve. This was not clearly
communicated to the user and they expected this to be a setting per
CurveMapping.
This change will move the option from `Curve` to `CurveMapping`. In
order to support this the API had to be changed.
BPY: CurveMap.evaluate is also moved to CurveMapping.evaluate what
breaks Python API. Cycles has been updated but other add-ons have
not. After release of 2.81 we can merge this to master and adapt
the add-ons.

This is a regression since PBVH was introduced for weight paint.
The solution is: treat subsurf and multires modifiers as deforming
ones for the weight painting. This is an easiest solution to make
PBVH use subdivided location of original vertices.
This change could simplify some of the weight paint by removing
the grids check, since PBVH is not supposed to be built from grids
in this case anymore.

Grab active vertex snaps the maximum strength of the grab brush to the highlighted active vertex, making it easier to manipulate low poly models or meshes with subdivision surfaces.
Dynamic Mesh Preview generates a list of connected vertices from the active vertex and draws them from the cursor code. This helps to visualize the real geometry the user is manipulating from sculpt mode when there are active modifiers.

We need to find a better solution for mixing normal refreshes in some corner
cases. We actually had similar issues in 2.79 anyway, not crashing is more
important.
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.
Centralize logic for when to use the PBVH for drawing, fix missing tests in
mask drawing, fix missing tests for multiple windows, only do more expensive
update for all viewports at end of the stroke.
In 2.7x UV sculpt was a kind of sub-mode
(a toggle with it's own key-map & drawing code).
Move this to an operator that uses the tool-system,
this simplifies internal logic, especially brush selection
which now matches sculpt and other paint modes.
- Remove toggle used to enable uv sculpt.
- Expose the brush, which was already used but there was no way to
select different brushes.
- Make UV sculpt use paint paint tool slots
(using brushes how all other paint mode currently do).
- Move UV Sculpt keymap to the tools keymap.
- Remove Q to toggle UV sculpt mode,
S/P/G keys to switch tools.
