Brian Birtles ac47cd0a02 Bug 1112480 part 6 - Make PendingPlayerTracker call StartOnNextTick; r=jwatt
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).
