This patch switches on the new, "actually start the player in the next refresh driver tick" behavior. It updates PendingPlayerTracker, adding a StartPendingPlayersOnNextTick method which calls the appropriate method on AnimationPlayer. The existing StartPendingPlayers is renamed to StartPendingPlayersNow and is used for testing only. Furthermore, since we now expect AnimationPlayer::StartOnNextTick to be functional, AnimationPlayer::DoPlay is updated to use it when there is no document available. This should make playing an animation player always asynchronous, that is, always transition to the pending state temporarily (unless we are already playing).
