Subject: [PATCH] build, qml: Explicitly disable experimental Direct3D 12
 adaptation

The Direct3D 12 adaptation is an alternative renderer for Qt Quick 2
when running on Windows, both for Win32 and UWP applications.
Currently, being enabled it causes an error in Guix build for the
x86_64-w64-mingw32 host.

See: QTBUG-79925, QTBUG-86892.
