vc4: Throttle outstanding rendering after submission.
Just make sure that after we've submitted, we get to at least 5
(global) submits ago before we go on to do more. Prevents up to
seconds of lag with window movement in X with xcompmgr -c. There may
be useful tuning to do in the future, but for now this gets us
usability.
