[web-animations] accelerated animation with view progress timeline range and
a scroll time yields a crash
https://bugs.webkit.org/show_bug.cgi?id=314104
rdar://176274648
Reviewed by Anne van Kesteren.
If the timeline associated with an animation is a plain scroll timeline, but
not a view timeline,
we must resolve any offset using a view progress timeline range by simply
disregarding the keyword.
This ensures we have resolved computed offsets in such a case, ensuring we do
not crash when attempting
to create the `AcceleratedEffect` representation for this keyframe effect.
