[libc++] Remove obsolete Solaris and Newlib support for locales (llvm…

…#113721) The solaris header file doesn't even exist, so that's definitely dead code. The newlib header is empty, which means that localization can't work on that platform. If someone is using libc++ with Newlib, they must be providing LIBCXX_HAS_NO_LOCALIZATION today for anything to work, so that header is basically dead code as well.
