Depsgraph: store mode and time in depsgraph, add view layer / scene accessors.

Scene, view layer and mode are now set in the constructor and never changed.
Time is updated on frame changes to indicate which frame is being or has been
evaluated last.

This is a step towards making EvaluationContext obsolete.
