  [libc++][NFC] Add a static assertion to document an assumption in std::hash (#114440)

The implementation of std::hash for unsigned long makes the (correct)
assumption that size_t is at least as large as unsigned long. If that
were not the case on a platform, the implementation of std::hash for
unsigned long would be absolutely terrible. Add a static assertion to
document that assumption.
