Fix T77328: Crash on undo Draw Face Sets stroke with dyntopo active
Draw Face Sets does not work in Dyntopo and the sculpt API should be
responsible for that without needing to add checks all over the code,
but it was doing an undo push of type SCULPT_UNDO_FACE_SETS which is not
supported, causing the crash.
