Run headers_clean check with C++20 (gcc, clang)
The headers are already somewhat tested with C++17 in the regular
build. So let's try in the headers_clean check with C++20 instead.
Using C++20 with MSVC 19.28 doesn't work yet though:
corelib/tools/qalgorithms.h(247): error C2039: 'popcount': is not a member of 'std'
corelib/tools/qhashfunctions.h(311): note: see declaration of 'std'
corelib/tools/qalgorithms.h(247): error C3861: 'popcount': identifier not found
...
