We replace `layout.css.scroll-driven-animations.viewtimeline.enabled` with `layout.css.scroll-driven-animations.enabled`. This preference was added because we used `double` to replace `CSSNumericValue`. Now we have updated the WebIDL to match the spec, so we could just use the preference of scroll animations instead. (And so we enable this interface on Nightly, for the interop purpose.) Differential Revision: https://phabricator.services.mozilla.com/D304653
