Merge branch 'master' into override-recursive-resync

adaptive_cloth: `do_step_cloth()` should update the input mesh

Merge remote-tracking branch 'origin/master' into temp-lineart-contained

adaptive_cloth: `clothModifier_do()` returns a new `Mesh` if simulation was successful

This is an important change that allows for remeshing operations in
the cloth simulator. `clothModifier_do()` returns the resulting mesh
if it was successful otherwise NULL.

USD dome light export improvements.

Moved code for exporting the environment dome light to
a new world_material_to_dome_light() function. This
logic now includes support for exporting the environment
texture and for using a relative path for this asset.
Also added logic to export the dome light properties
using a naming scheme backward compatible with USD
versions older than 21.

Support reading per vertex UVs on a meshes.

rebaseing and cleanup

Support reading UVs at the vertex scope.

Such UVs may be generated by Houdini or Maya.

makeing node and modifier working with solidify kernel version.

- added offset and boundary data enums for nonmanifold mode.

- selection for simple

make selection work for complex mode

moved solidify to Blender Kernel

Initial setup for solidify node

solidify_extrude_generaly working.

- working with data from node

- added basic support for input data

Cleanup: Even more unused functions in Cycles X pass

Didn't notice those in the previous cleanup.

Cleanup: De-duplicate pass find logic

The code of `Pass::contains()` and `Pass::find()` was almost identical.

Cleanup: Remove unused pass functions in Cycles X

Additionally, the comparison function was wrong: was using same vector
of passes to get the next indices.
