[@container] Add support for scroll-state(overflowing) axis
Add new values for matching axis instead of edge for overflowing: block, inline, x, y. These are convenience keywords. For instance: scroll-state(overflowing: x) is the same as: scroll-state((overflowing: left) or (overflowing: right)) Based on request in [1] [1] w3c/csswg-drafts#11183 Bug: 367764865 Change-Id: I125db5e5eced86da6404aa0bc5469830278d0ca9 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/6022915 Reviewed-by: Anders Hartvoll Ruud <andruud@chromium.org> Commit-Queue: Rune Lillesveen <futhark@chromium.org> Cr-Commit-Position: refs/heads/main@{#1386111}
