Christian Hergert 53616a73e9 gdk/wayland: use wp_presentation for more accurate frame timings 
This attempts to improve the accuracy for the "presentation_time" of an
individual GdkFrameTimings. That information is currently filled in as soon
as we get a frame callback. However, if presentation-time wayland protocol
is available, that will be used to supliment a more accurate time which
may improve future presentation-time predictions within GdkFrameClockIdle.

The protocol states that all related and sub surfaces will receive the
same information so it is safe that this could be registered for more
than just the toplevel. The information becomes idempotent.
