  [web-animations] add a dedicated timeline object for accelerated effects
https://bugs.webkit.org/show_bug.cgi?id=253312

Reviewed by Dean Jackson.

Add a new AcceleratedTimeline class on which elements targeted by effects animating
accelerated properties are registered. Then as the document's timeline is updated,
we go through these registered elements and update the accelerated effect stack for
them through their RenderLayerBacking.
