Sculpt: Scale Cloth Filter

This filter scales the mesh as it was a softbody, producing folds in the
surface. The orientation of the folds can be controlled using the filter
axis and orientation.

This is an example of a cloth filter that uses deform coordinates instead
of forces, but probably it does not make much sense to expose it to the
user in a different way and with different parameters. I'll remove
FilterCache->enabled_force_axis in a later commit and use always
enabled_axis in SCULPT_filter_zero_disabled_axis_components
for both forces and deformation filters, so this function can also be used
in the mesh filter.

Sculpt: Lower the default cloth deformation constraints strength

The deformation constraints strength were too strong and they were
preventing the cloth effects of the brushes with cloth deformation target
to create folds properly. This lowers the default, making the simulation
follow the deformation in a more relaxed way.

I'll make a separate patch to expose this as a property for certain brushes
and cloth deformers that may need higher values (like boundary with loop
falloff on a low poly mesh), but I think this default will work better for
most use cases.

This commit caused regression on some sculpt paint cursors. A better

GPencil: Implement Holdout materials

This new feature allows to use the strokes as an eraser of any stroke below. This is very handy to open holes in filled areas.

After running some tests, we have decided to keep the additive effect of the holdout color. To get clean holdout areas, just move the color to black to remove any additive effect. To have additive effect can be used in situations like tint slightly a transparent window with blue to simulate the glass.

Fix warning printed when duplicating marker

Steps to reproduce were:
* Create a marker in the timeline
* With the mouse over the marker region, press Shift+D

The function for moving markers was reused and had handling specific to
tweak events. This is not relevant in case of duplicating markers.

UI: Correct superimposed icon interaction hotspot

The hotspot was slighly too large, which could be apparent in cases

Fix T80927: UV Edges Not Visible When Repeat Image Active

CMake/LLVM: Add INCLUDE_DIRS to find package.

CMake/OpenSubdiv: Rename INCLUDE_DIR -> INCLUDE_DIRS.

Ref {D8855}

Unix and Apple platform files use find_package(OpenSubdiv) which sets
`OPENSUBDIV_INCLUDE_DIR` as an advanced variable, as well as
`OPENSUBDIV_INCLUDE_DIRS` which should be used usually.
Windows sets `OPENSUBDIV_INCLUDE_DIR` which is used by the rest
of the code.

This patch renames it to `_DIRS` everywhere, for it to be like other
similar variables.

Fix T80900: Crash lasso-selecting in particle editmode in certain
situations

In the situation that the PTCacheEdit is not available (e.g. when
editing unbaked Cloth or Softbody caches - or, as in the report, being
in Cloth or Softbody Editing Type for Hair particles), accesing the
corresponding ParticleSystem or ParticleSystemModifierData would crash.

Now access these later (after PE_start_edit had the chance to return
early on this non-valid situation).

Fix T80437: Auto IK Double Generates IK constraints

Caused by rB9a7f5f1bb422.

If using Auto IK (or targetless IK and Auto IK together), two temporary
constraints were added.
- from pose_grab_with_ik_add (even for targetless IK)
- from add_pose_transdata (even for Auto IK)

Since both both do similar things, but cannot work in tandem (with
possibly different chainlengths for example), we have to decide which
type to prefer over the other (as in: do not create a constraint for the
other).
It seems better to ignore the 'Auto IK' option on bones that will
have targetless IK set up for them specificallly [e.g. defining special
chainlength]. This way you can still work with 'Auto IK' ON generally
[with interactive chainlength control], but also have specific bones that
need their own custom chainlength.

For now, the most straightforward fix is to
- only add constraints for Auto IK from pose_grab_with_ik_add()
- only add constraints for targetless IK from add_pose_transdata()

Note: this area has some potential for later refactoring:
- move creation of all temporary constraints to a single place
[preferably pose_grab_with_ik_add]
- use only those temporary constraints in transform code [atm. we still
flip CONSTRAINT_IK_AUTO around on the "original" -- unneccesarily, after
rB9a7f5f1bb422 a dedicated temporary constraint is now always available]
- clarify CONSTRAINT_IK_AUTO vs. CONSTRAINT_IK_TEMP
- obeying standard rotation locks on bones in the chain (not just the
the IK locks) is not consistent between targetless IK and Auto IK

Potential candidate for 2.90.1 as well as 2.83 LTS
