Carlos Garnacho b588baf9f5 compositor: Add MetaFeedbackActor
This actor is a non-reactive container that autoembeds itself into
the feedback window group in the compositor. The API is meant to
help on creating things attached to pointer/touchpoints, with an
X/Y attachment offset, and following the position of certain events.
