BLI_math_matrix: add invert_m4_m4_safe_ortho (m3 version too)

Unlike invert_m4_m4_safe, this calculates zeroed axes.
Useful when we need to use the inverse of an objects matrix,
keeping the valid axis, only filling in the zeroed ones.

Sculpt: Cloth Snake Hook Brush

This implements Snake Hook as a deform type for the cloth brush. This
brush changes the strength of the deformation constraints per brush step
to avoid affecting the results of the simulation as much as possible. It
allows to grab the cloth without producing any artifacts in the surface
and create more natural looking folds than any of the other deformation
modes.

Fix T80008: Smooth brush not deforming mesh boundaries correctly

In 2.83 and previous versions there was a bug that was causing boundary
vertices to be detected incorrectly that was preventing the smooth brush
to work on boundaries if there was a pole on them.
In 2.90 the boundary vertex detection was fixed, but it was still using a
simplified version of the algorithm without any boundary smoothing. This
patch implements a similar smoothing algorithm to what I think it was
the intention of 2.83 and previous versions, but working correctly.

This is quite embarassing... it was returning the base instance instead of
the correct vao. No wonder that it was causing crash and at most drawing
issues.

Fix T80039: Do not subdivide with Multires is mesh has no faces

This skips the subdivision operation if the mesh has no loops, avoiding

Fix T79819: crash with OSL trace() and getmessage() after Embree changes

Fix T80076: Cycles Alembic Motion Blur Problem

The problem occurs when a deforming modifier is added to the object
after the MeshSequenceCache modifier. We should only consider the cached
velocities if the MeshSequenceCache modifier is the last one on the
object and we also need to check for the correct vertex count before
adding the motion vertex attribute.

Cycles: cleanup, remove unused parameter

This parameter was introduced during a revision of the Alembic motion
blur patch, and is not needed anymore.
