Remove a hack at least for Emscripten --enable-qt6

That "no idea, why Qt::WA_NativeWindow breaks the menubar for EMSCRIPTEN" had
been added in c3d25b55990e2205af56747aa2935f4ff11ad0aa "WASM Qt: various
EMSCRIPTEN adaptions", but with no explanation beyond "Don't create a native
window handle".  At least for recent Qt6 dev (towards Qt 6.10), that doesn't
appear to cause any (obvious) issues, however, but would cause some
"qt.core.qobject.connect: QObject::connect(QWindow, QtFrame): invalid nullptr
parameter" console log from
