[animation-worklet] Send state from cc to worklet and back.

The patch introduces the followings:
 - cc::WorkletAnimationPlayer: A type of animation player that has a
   local time and a name. This class overrides Tick method to use
   its own local time to tick its animations.
 - Add appropriate hook in AnimationTicker to allow external party to
   control the time used for ticking an animation.
 - cc::Mutator{Input,Output}State: structs that are used to shuttle data
   to/from cc to animation worklet.
 - Update LayerTreeMutator::Mutate to accept input state
   add LayerTreeMutatorClient::SetMutationUpdate that takes output state.
 - Collect input state in AnimationHost when sending mutate signal to
   AnimationWorklet and then apply output state once we receive the
   result back.
 - Update AnimationWorkletGlobalScope to take input state and update its
   animators accordingly.
-  compositorworker/EffectProxy.idl: A placeholder object that can be
   used in animator animate callback to set a local time. These are then
   plumbed back to the corresponding worklet player in cc.
