QWindow: prevent window reparenting into Qt::Desktop windows
Qt::Desktop exists to support QDesktopWidget, which predates the QScreen
API. QWidget internally has checks that prevents you from reparenting a
QWidget into a QDesktopWidget, so we should have the same limitations on
the QWindow level. This allows platform plugins to implement Qt::Desktop
as simple (possibly shared) wrappers around QScreen without having to
allocate native window resources for each desktop window.
