[libc++] Mark some recent LWG issues and papers as done (#87502) Justifications: - LWG3950: Done in #66206 - LWG3975: Wording changes only - LWG4011: Wording changes only - LWG4030: Wording changes only - LWG4043: Wording changes only - LWG3036 and P2875R4: We implemented neither, but the latter reverts the former, so now we implement both without doing anything!
