Sculpt: Mask Init operator

This operator initializes mask values for the entire mesh. It supports
different modes for initializing those values, and more will be added in
the future.

The initial version supports generating a random mask per vertex, Face
Sets or loose parts. These masks are useful for introducing variations
in the model using the filters (both shapes and colors).
