[Qbs] Windows 11 & (major|minor)-subsystem-version

Someone reported an issue a while ago and I created a ticked just yesterday in order to to not forget it.

I suppose, the issue was introduced by this patch https://codereview.qt-project.org/c/qbs/qbs/+/459921 which was an attempt to fix Qbs build with mingw - mingw headers are broken in a way that the old value leaded to incorrect macros in Windows.h

If you find a way to fix Qbs build and actual binaries, you’re welcome to submit a patch.

Note that CMake sets (major|minor)-subsystem-version to 0 (unconditionally?) when building for mingw.
Maybe you can set those to 0 for _linking_ while setting the correct WINVER/whatever macro Qbs sets for _compiling_.

Also, this should be fixed by mingw upstream - otherwise those flags are useless.

> I've inspected a few programs, I've found none which didn't set the value (and the os version too by the way) to anything higher than 6. That includes the CMake generated Qt programs (moc, qmake, etc.) and Microsoft programs like Notepad, Teams, and Outlook.
