ba15d186e5 [clang] Use -std=c++23 instead of -std=c++2b
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.

834a878367 [C++2b] [Modules] Handle HaveModules with C++2b
Closing https://github.com/llvm/llvm-project/issues/56803. The root
cause for this bug is that we lack a good method to detect the language
mdoe when parsing the command line. There is a FIXME too. Dut to we lack
a good solution now, keep the workaround.
