shield _artifact_str function behind a world age barrier (#58957)

We already do this for `require` in Base loading, it probably makes
sense to do this here as well, as invalidating this function easily adds
+1s in load time for a jll. Avoids the big load time penalty from
loading IntelOpenMP_jll in
#57436 (comment).
