Template specializations of std::hash for the various view classes for hashing views.
These hashes equal the hashes of corresponding std::basic_string classes: If S is one of the standard basic_string types, SV is the corresponding string view type, and s is an object of type S, then std::hash<S>()(s) == std::hash<SV>()(SV(s)).
