  [scroll-animations] add parsing support for the `scroll()` notation of the `animation-timeline` property
https://bugs.webkit.org/show_bug.cgi?id=265786

Reviewed by Antti Koivisto.

We now add parsing support for the `scroll()` notation of the `animation-timeline` property using a new
`CSSValue` subclass: `CSSScrollValue`. This will yield an anonymous `ScrollTimeline`.
