Use !QT_CORE_REMOVED_SINCE(6, 7) to make the function a template
in new C++20 code. The removed_api.cpp will still compile the
exported version, keeping BC.
This simplifies the ifdef'ery around the functions and saves the
need for the QT6_{DECL,CALL}_NEW_OVERLOAD trick.
Picking this change down to 6.7, because the original patch was
also picked to 6.7.
Tested it on MSVC in C++20 mode, and verified that the symbol
is still there. Also tested the case from the linked bugreport,
and verified that it does not give linker errors.
Amends 88702cc87cf830b145c8bff5174748e3719364f9
and effectively reverts 91f48cc4b77b1cfb5a4490c3bed3eb97edd2f85a.
Task-number: QTBUG-125610
