  [web-animations] add a class to store accelerated effects and base values
https://bugs.webkit.org/show_bug.cgi?id=253238

Reviewed by Dean Jackson.

Add a new AcceleratedEffectStack class which we will use to store a sorted stack
of accelerated effects and the base values to be used for blending on platform layers.

Since there are separate layers for backdrop-filter and all other accelerated properties,
we separate the set of effects passed to AcceleratedEffectStack::setEffects() between
effects that will target primary layers and those affecting backdrop layers.
