Avoid requesting multiple sync for display rotation

Previously, collect(display) always requests all window prepare
sync. And AsyncRotationController may request another sync by
applyWithNextDraw, which may cause stale sync state and the
window is unable to apply its draw transaction.

Now the prepareSync from display will only sync the windows
that AsyncRotationController doesn't handle.
