  [libc] Validate against LC_ALL_MASK in newlocale (#194514)

Currently, `newlocale` uses `LC_ALL` for validation, but it's supposed
to the `LC_*_MASK` category of constants
(https://pubs.opengroup.org/onlinepubs/9699919799/functions/newlocale.html).
Pretty inconsequential since LLVM-libc doesn't actually support locales,
but this popped up since libc++ wants to be able to call `newlocale` and
not receive a `nullptr`.
