vblankmanager: Put some of the vblank redzone into a min value
...
Just matters that we call drmAtomicCommit before 1.6ms, we can keep this value more stable for 99% of cases this way.

vblankmanager: More value tuning
...
Based on some rough data across a variety of games that are both GPU bound and also ones that are very not and cause GPU clocks to vary wildly

vblankmanager: Estimate draw buffer time based on max rolling average draw time

Handles spikes much better and allows us to have a lower buffer when not needed.

Stop using X11 events for vblankmanager
...
Instead, use a pipe. Check if the pipe is readable in the
steamcompmgr event loop.
This avoids a roundtrip through the X11 server.

vblankmanager: initial system to let steamcompmgr know when to repaint
...
For now just mark one repaint per refresh interval without any particular
alignment, as that can be hard to get in nested. We'll use the display
timing extensions for that later.
We'll have it align properly in embedded mode soon.
