Reland "Remove before/after phase and scroll offsets."

This is a reland of commit 079c3deabde9f92b24e4b8746ee883e8b729c275

Original patch introduced a compile failure due to v8_edge still
being referenced as part of the build. Fixed generated_in_core.gni,
and removed the stale idl file.

Original change's description:

Remove before/after phase and scroll offsets.

This patch removes deprecated pieces of code from scroll-timelines based
on resolutions and direction in the spec rewrite.

https://drafts.csswg.org/scroll-animations-1/rewrite

Scroll timelines no longer have settable offsets. Instead, each
timeline has a single inferred pair of offsets. For the base
ScrollTimeline class, this is presently based on the scroll range. For
ViewTimelines, the range will likely be based on enter-start to
exit-end (deferred to a followup patch).
