During the ISO C++ Committee meeting plenary session the C++23 Standard has been voted as technical complete. This updates the reference to c++2b to c++23 and updates the __cplusplus macro. Drive-by fixes c++1z -> c++17 and c++2a -> c++20 when seen. Reviewed By: aaron.ballman Differential Revision: https://reviews.llvm.org/D149553
