[libc++] Add missing annotations for TEST_HAS_NO_WIDE_CHARACTERS

Those tests would pass when run on a C Standard Library that actually
provides wide characters, but fail when run on top of one that doesn't.
It's really difficult to test this 100% perfectly in the CI without
introducing an actual platform that doesn't provide these declarations.
