Boris Chiou a583c59406 Bug 1921116 - Use a hash map to handle animation data for pseudo elements. r=view-transitions-reviewers,emilio
Also, we put view transition psuedo element into
`AnimationUtils::IsSupportedPseudoForAnimations()`, and update the handling
of getting the pseudo request from a frame, to make sure we retrieve the
correct data for all supported psueod elements.

Besides, we have to update `SortingIndex` so we sort the events properly and
avoid hitting the assertion when using view-transitions.

The tests will be added when we support getAnimations() (Bug 1921109).
