I made a new backport attempt in #139468, let's see if it works. If not, it seems like the libcxx CI on the release branch is broken wrt macOS, and we can either choose to ignore it in all libcxx backports to 20.x, or just stop doing backports touching libcxx to this release branch (or we'd need to do even more CI fixing for the release branch).
