Drop multiple timelines and relevant concepts for Animation Worklet.
This also drops the hide-bar example from spec. I may re-work this example (e.g., switching timeline via setting animation.timeline on main thread) and add it back this in future but for now dropping it is simpler.
Multiple timeline was originally the solution that would allow seamless switching between between
scroll timeline and regular timelines. Since then we have iterated over multiple different solutions.
See #834 for a list of various design we have considered. It seems that allowing events to be handled
in Animation Worklets will enable the relevant usecases.
For now we drop multiple timelines fromAnimation Worklet Level-1 to ensure simplicity and better alignment with WebAnimations.
