Free Debreuil 2e2f1a4034 Bug 2052935 [wpt PR 61095] - Make scroll timelines support single-axis scroll containers, a=testonly ...

Automatic update from web-platform-tests
Make scroll timelines support single-axis scroll containers

Scroll timelines set to `nearest` and view timelines now resolve to the
nearest ancestor scroll container for the requested axis. For these
cases, the writing mode of the nearest ancestor scroll container is
used.

Add the writing mode used to resolve logical axes to the timeline
snapshot, and hook this up to the compositor timeline.
