  [threaded-animation-resolution] add support for blending `transform` values
https://bugs.webkit.org/show_bug.cgi?id=269226

Reviewed by Simon Fraser.

We've added the general system to blend accelerated properties with 274102 at main.
We now add support for blending the transform-related properties affecting the
`CALayer.transform` property. To do this, we need to provide the `RemoteAcceleratedEffectStack`
with the bounds of the targeted layer. Note that we don't yet account for the
various properties defined by CSS Motion Path, but only account for the CSS
properties `transform`, `translate`, `scale` and `rotate`.
