Depsgraph: Make bAction a part of dependency graph

There are various values which depends on context in there, for example
current driver value and original DNA value f-curve is applied for.

This partially fixes issue with not being able to tweak keyed values
when material preview is open.

The material preview is not being currently updated against non-keyed
changes since every tweak of material property does full preview scene
depsgraph evaluation.
