backends: Add logical monitor -> monitor -> output -> crtc ref chain

Browse Source 
Make it so that each logical monitor has a reference to all the
monitors that are assigned to it.

All monitors has a reference to each output that belongs to it.

Each output has a reference to any CRTC it has been assigned.
