Depsgraph: Don't force copy-on-write when shading changes

Shading is supposed to be dealing with draw manager batch cached
thingamajigs, but was causing full object update.

This was causing both flickering in sculpt mode (PBVH was removed,
why it was SOMETIMES restored before draw is a mystery), and was
also causing things to be really slow.
