Joerg Bornemann b5ed3cb7ba qmake: Add support for C++23
Add the CONFIG value c++2b that represent the upcoming C++23 standard.
Add QMAKE_CXXFLAGS_CXX2B and QMAKE_CXXFLAGS_GNUCXX2B.
On MSVC, use /std:c++latest when c++2b is active.

This fixes an issue with MSVC where c++latest implied the /std:c++20
compiler flag.

Pick-to: 5.15 6.2 6.3
Fixes: QTBUG-102202
