Nick Desaulniers 7c59e8001a Reland: [Demangle] replace use of llvm::StringView w/ std::string_view
This reverts commit d81cdb49d74064e88843733e7da92db865943509.

This refactoring was waiting on converting LLVM to C++17.

Leave StringView.h and cleanup around for subsequent cleanup.

Additional fixes for missing std::string_view conversions for MSVC.
