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.
