This enables/disables adaptive synchronization on the output. For now, the default is disabled because it might cause flickering on some hardware if clients don't submit frames at regular enough intervals. In the future an "auto" option will only enable adaptive sync if a fullscreen client opts-in via a Wayland protocol.
