Boris Chiou 74f0bd8a0c Bug 1676791 - Part 8: Hook scroll-timeline rule into Cascade data and use it for CSS animations. r=emilio,hiro
We hook the rule into cascade data, and so we can look it up by timeline
name. Now we only use StyleScrollDirection from @scroll-timeline rule.
`source` and `scroll-offsets` are skipped now and use the default values
instead because I'm pretty sure the syntax will be changed in Bug 1733260,
and `scroll-offsets` may be obsolete because the spec proposal intents to
make it be always 0% ~ 100%.

Also, add some reftests for the default `source` and `scroll-offsets`,
and different `orientation`s.

Besides, we disable at-scroll-timeline-start-end.html in Gecko because
we don't support start/end descriptors, and there are too many
intermittents in it.
