qmake: Allow using Windows 10 API in MinGW qmake internal projects

When trying to build qt3d examples with qmake and MinGW in the CI,
compilation would fail with errors like

 In file included from
 C:/MINGW1120/mingw64/x86_64-w64-mingw32/include/windows.h:72,
 from C:\Users\qt\work\qt\qt3d\examples\qt3d\simple-cpp\main.cpp:63
 include/winuser.h:2965:72: error: 'POINTER_INPUT_TYPE' was not
 declared in this scope

What happens is that calling qmake on examples.pro loads
qt3d/.qmake.conf, which then loads qt_build_config.prf which then
defines the following definitions:

 mingw: DEFINES += WINVER=0x0601 _WIN32_WINNT=0x0601

This limits usage of Windows API up to Windows 7, with later APIs
being unavailable.

Most .qmake.conf files were removed in qt repos, but We didn't remove
the .qmake.conf file (fb656c036db0549180073e133773862d08f6cd24) for
qt3d because it's supposed to be buildable with CMake + Qt 6 as
well as qmake + Qt 5.

Bump the defines to the same Windows 10 version we use everywhere else
when building with CMake.
