Sculpt: Cloth Filter

This tool is similar to the cloth brush, but it applies the cloth
simulation deformation to the whole mesh in an uniform way. The
simulation can be controlled using the mask to pin vertices and the face
sets to define force action areas.

It uses the same solver as the cloth brush which now no longer depends
on StrokeCache.
