Depsgraph: Move storage from single per-scene depsgraph to a hash storage

Depsgraph itself is still created fer the whole scene rather than for a
single layer, this is to be addressed next.

The storage for those dependency graphs is in scene, but now it is a hash
indexed by layer. In the future we can extend hash key to include extra
information (workspace? window?).
