Fix T79622: Mesh Filter on a locked Shape crashes

For a locked shapekey, a SculptSession's orig_cos / deform_cos /
deform_imats are not initialized (they only are when
deform_modifiers_active is true -- this in turn is only true for
shapekeys if they are //not// locked [and for deforming modifiers of
course])

We can just update that keyblock with sculpt_update_keyblock() in case
of a locked shapekey

Fix T79712: Color Changes do not record in Auto-Key Mode

Caused by rBfffba2b6530.

In above commit, the buttons rnaindex [-1 for entire arrays like colors]
was not used anymore for the entire function body of
`ED_autokeyframe_property` (previously in `ui_but_anim_autokey`).
Replacing the index with 0 (in the array case) is indeed necessary for
`BKE_fcurve_find_by_rna_context_ui`, prior to rBfffba2b6530 this was
taken care of by using `ui_but_get_fcurve` instead [which did this
internally].

But using an index of 0 (instead of -1) for the entire function body of
`ED_autokeyframe_property` fails for the array part later, namely
`insert_keyframe` needs -1 here.
Now just replace the index for //finding the FCurve//, but use the
original for //inserting the keyframe//.

Could be backported to 2.83 LTS.

Cleanup: use standardized macro instead of __attribute__

Checking for PWN.

The current code is only supposed to work if the input meshes
are "piecewise constant winding number" (PWN). Added a check
to see if this is true about the inputs.

Cleanup: compiler warnings

Fixes T77882: artifacts rendering OpenVDB volumes with multiple grids in Cycles

The previous algorithm was not using all of the requested grids to build a mesh
around the volume due to limitations regarding the use of a dense buffer to
gather information about the volume's topology. This resulted in artefacts during
rendering.

The mesh generation is now done by merging all of the input grids and using the
resulting grid's topology to create the mesh. The generation of the mesh
is still done in index space as before, and the vertices are converted to object
space by using the merged topology grid indexToWorld transform.

To be able to merge the grids together we have to make sure that their transformation
matrices and their index spaces match, thus, if they do not match we simply resample
the grids. This behaviour should tackle one other limitation of the current algorithm,
which is that only one transformation matrix was used to generate the final mesh.

If we do not have an OpenVDB grid for the requested volume data, we generate
a temporary OpenVDB grid for it.

Fix UV unwrap not working with only one pinned vertex

Now the one vertex defines the position of the UV chart, while rotation and
shape is still determined automatically.

Bump the minimum required version for 2.90

This is particular important because 2.90 will coexist with 2.83 LTS, so
we should warn the users of potential loss of data when going from 2.90
to 2.83 and back.

Cleanup: Use proper bool type and literals for operators poll functions.

Fix (unreported) broken Poll function of GPencile mods and ShaderFX operators in liboverride case.

Those where assuming we always get a valid modifier data from context,
which is not always true...

Also fix similar issue with shortcuts as reported in T79635.

Fix part of T79635: Disable by default operation on unknown mod from liboverride object.

It is unfortunate that we cannot get active modifier from context when
operator is called from a shortcut, but we'd need an event for this to
work... So for now forbid any modifier operation of liboverride objects
in that case.
