Depsgraph: Begin bringing API to pass explicit graph

This is a first step towards an updated API where we pass explicit graph rather
than a scene. This is because we can no longer deduct which graph to use since
it will depend on a context.

Will happen in several steps, so bisecting will not be such a pain.
