d6089c91 - [cxx-interop] Conform `std::string` to `ExpressibleByStringLiteral`

[cxx-interop] Conform `std::string` to `ExpressibleByStringLiteral` This allows `std::string` to be constructed implicitly from a String literal, which is convenient e.g. when calling C++ APIs that take `std::string` as a parameter.
