output: introduce wlr_output_event_commit

Browse source 
This event contains a `committed` bitfield, which allows callers to know
which output fields changed during the commit.

This allows users to setup a single atomic commit listener, instead of
setting up one listener for each event (mode, scale, transform, and so
on).
