Masks: Properly port to Copy-on-Write concept

Authored by Sergey Sharybin (sergey) on May 21 2019, 6:18 PM.



Masks were not really covered by Copy-on-Write due to mistake
in the dependency graph. After correcting that mistake a lot
of tools became broken, so majority of the patch is related
on making it so access to evaluated/tessellated masks is done.

When accessing evaluated mask state make sure access to an
evaluated dependency graph is done. This solves possible
access to NULL data on redo.

Fixes T64899: Re-doing new point addition causes crash
