Reviewed by Simon Fraser.
The `steps()` easing takes a "before" flag [0] that we only passed when calling
`TimingFunction::transformProgress()` when resolving the overall effect
progress in
`AnimationEffectTiming::resolve()`.
But a `steps()` easing may be specified for a given keyframe interval, and as
such
the `TimingFunction::transformProgress()` call site in
`KeyframeInterpolation::interpolateKeyframes()`
needs to pass that flag in as well. We now expose that flag through
`ResolvedEffectTiming`
and `ComputedEffectTiming` such that we may ultimately pass it over to the
appropriate
method both in the non-accelerated codepath
(`KeyframeEffect::setAnimatedPropertiesInStyle()`)
and the accelerated codepath (`AcceleratedEffect::apply()`).
This makes the recently-added WPT test
`css/css-animations/jump-start-animation-before-phase.html`
pass since it used a `steps(1, jump-start)` easing in the before phase of a CSS
Animation.
