This is a follow-up to https://github.com/apple/swift/pull/35072. Let's wait until both sides are equally optional before attempting `.rawValue` fix, otherwise there is a risk that a valid code would get diagnosed. Extend test coverage of possible `.rawValue` situations to contextual and argument positions to make sure that valid code is accepted. Resolves: SR-13951
