PBVH: PBVH_FullyMasked and PBVH_FullyUnmasked flags

This commit introduces flags to tag the PBVH nodes as fully masked or unmasked. This is used in do_brush_actions to filter fully masked nodes during a stroke. Other tools can also be updated to use this flags.
Sculpt updates now require a flag to update the mask or the vertex coordinates.
