Split animations and transitions into separate lists

Browse source 
This change splits the list of animations and transitions, which are
almost always handled differently. It also renames
`ElementAnimationState` to `ElementAnimationSet` and establishes an
`AnimationState` for every transition and animation. This allows us to
stop continually reallocating lists every time a transition or animation
needs to be canceled.

Fixes #14419.
