Sculpt: Fix T101864: Mask initialization not updating multires data

BKE_sculpt_mask_layers_ensure now takes a depsgraph argument and
will evaluate the depsgraph if a multires mask layer is added.
This is necassary to update the multires runtime data so that
pbvh knows it has a grids mask layer.

Also added code to update pbvh->gridkey.
