[libcxx-commits] [libcxx] [libc++] Guard transitive include of `<locale>` with availability macro (PR #95686)

[Konstantin Varlamov via libcxx-commits]

https://github.com/var-const created https://github.com/llvm/llvm-project/pull/95686

This is a follow-up to https://github.com/llvm/llvm-project/pull/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>`.
