Present: add PresentPixmapSynced
Adds an augmented version of PresentPixmap supporting explicit
synchronization with a direct rendering device. This takes the form of
timeline DRM synchronization objects, along with acquire and release
points on those timelines. Implementations advertising
PresentCapabilitySyncobj will wait for the acquire point to be signaled
before executing the PresentPixmap request, and signal the release point
after any GPU operations on the pixmap have completed.
