[threaded-animation-resolution] add support for blending `opacity` values
https://bugs.webkit.org/show_bug.cgi?id=268738
rdar://122304627
Reviewed by Simon Fraser.
In order to add support for blending `opacity` values we make
`AcceleratedEffect`
adopt the `KeyframeInterpolation::interpolateKeyframes()` method and its various
callbacks to deal with `AcceleratedEffect::Keyframe` values. We wrap this into
the new `AcceleratedEffect::apply()` method which is called from
`RemoteAcceleratedEffectStack`
in the `computeValues()` method.
We compute the blended values in three different places in
`RemoteAcceleratedEffectStack`.
When we resolve effects on the main thread (macOS) we have an
`initEffectsFromScrollingThread()`
method to initialize the `CAPresentationModifier` objects which will apply the
blended
values, and then on subsequent display updates we call
`applyEffectsFromScrollingThread()`.
When we resolve effects on the scrolling thread (iOS) there is no
initialization step
required and the single `applyEffectsFromScrollingThread()` method suffices.
Future patches will add support for the other transform-related and
filter-related
accelerated properties.
