  [threaded-animation-resolution] use dedicated remote types for animations in 
the UI process
https://bugs.webkit.org/show_bug.cgi?id=300721

Reviewed by Dean Jackson.

In preparation for the support of multiple timeline types, we introduce a new 
`RemoteAnimation` type
for use within the remote render layer tree, and have such objects be managed 
by a `RemoteAnimationStack`
class that is no longer a subclass of `AcceleratedEffectStack`.
