The approach here is to lazily check if we have such animations. This allows
animations to be modified after being added to the pending animation tracker
(but not after HasPlayPendingGeometricAnimations is called since we cache the
result at that point) and avoids poor performance when calling
RemovePlayPending.

This is in anticipation of adding Animation::SetTimeline(). Once we set the
timeline out of band, there's a chance that getting it could return null so
this patch makes the WebIDL and method name reflect that.

This is needed not only for supporting other kinds of timelines, but also for
when we come to implement SetTimeline(AnimationTimeline* aTimeline).

This is not strictly necessary yet but we will want to implement methods
like GetAnimations() on the base class, AnimationTimeline, so we may as well do
that now rather than adding that code to DocumentTimeline and moving it later.

This patch also updates the method names on PendingAnimationTracker but leaves
a number of local variables which will be fixed in a subsequent patch.
