  6. vblankmanager: Port to timerfd 

    Ports vblankmanager to be timerfd based, and also fxies issues
with re-arming at higher refresh rates.

The old nudge thread method still exists (and is needed for VR), and
it has also been improved to fix the re-arming issue.

The old method can be enabled with GAMESCOPE_DISABLE_TIMERFD.

  7. vblankmanager: Treat wakeup time as scheduled wakeup point for timerf… 

    …d path

Because we are using timerfd, ulWakeupTime should actually be the target
point of the timerfd when using that, not the the current time from
OnPollIn, so we can account for the scheduling quantums from the target
wakeup time and other work (like we were wrt the pipe write before)
