Until C++23 is released, I would recommend not changing these macros.

The test macro is defined differently than the one in __config in an attempt to make it harder for people to depend on numbers that are not guaranteed to be stable.

The code `XXX_STD_VER > 20` will work for all standard versions later than C++20.
