Fix T80931: Proporional Editing Cursor Draws Incorrect

The incorrect view was setup so it was drawn in pixel space. This patch
changes it to use UV space.

Fix T80771: Avoid changing the visibility of loose geometry when entering Sculpt Mode

When entering scultp mode the visibility from the Face Sets is copied to
the base mesh. This steps was considering that if a vertex belongs to a
face with a visibible Face Set ID, it should be visible. As loose
geometry may not have any faces, those vertex were set to hidden.

Now this function check if a vertex visibility should be modified by the
face sets (by checking the loops), avoiding modifying the visibility of
loose geometry unintentionally.

Fix T79373: Forbid painting on linked image.

There is just no reason to support that kind of useless behavior.

Some remote TODO could be to define a process based on liboverride and
layers.

Fix T59272: dead particles not included in render, but visible in viewport

The issue was that the pointcache was not storing dead particles,
even though they are displayed. This lead to the rendering issue,
because only alive particles can be read from the point cache in
the frame that is rendered.

This also fixes an issue unrelated to rendering: when dead particles
are displayed, their position is incorrect when some frames are
skipped during playback.

Cleanup: Sculpt/Paint ED code: correct return constant types.

Mainly use false/true for bool, but also a few others.

No change in behavior expected.

Fix invert vertex group weight miscalculation for modifiers

Fix T78793, T79707: Cycles crash on macOS with older CPUs

Embree static libraries need additional linking flags to avoid SSE and
AVX symbols getting mixed up.

Cycles: Separate Embree device for each CPU Device.

Before, Cycles was using a shared Embree device across all instances.
This could result in crashes when viewport rendering and material
preview were using Cycles simultaneously.

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

Fix T80885: Texture paint camera project crashes after undo/redo

Add versioning for 2.90 files that may have invalid mesh

rBf2d26409e83b fixed a serious problem with invalid mesh after an
operation with the extrude manifold.

Since BKE_mesh_validate_arrays is a slow operation, the chosen
interval between versions is relatively small and also only the
mentioned invalid mesh problem is tested.
