[1.67-stable backport] Revert back to LlvmArchiveBuilder on all platforms

[pnkfelix]

ArArchiveBuilder doesn't support reading thin archives, causing a regression.

This is a backport of the third of three commits from PR #107360 (the other two commits are only relevant to 1.68-beta and nightly, not 1.67-stable).

hmm i guess I should figure out how to fix this

If it's just the problem with the version check, I can handle that when I pull together a complete release PR.
