[ADT] Implicitly convert between StringRef and std::string_view when we have C++17
This makes the types almost seamlessly interchangeable in C++17
codebases. Eventually we want to replace StringRef with the standard
type, but that requires C++17 being the default and a huge refactoring
job as StringRef has a lot more functionality.
