[libc++] Guard transitive include of <locale> with availability macro (#95686)

var-const · web-flow · commit 0cfdce854d58 · 2024-06-17T09:30:41.000-04:00
This is a follow-up to #80282. The transitive includes of `<locale>` in `<vector>` were all guarded by the availability macro -- the new include should also be guarded, otherwise any users who compile with localization disabled will start getting errors trying to include `<vector>`.
