To match the previous QWindow::orientation() property which can be
useful to access from QML. Also, removed the automatic translation of
Qt::PrimaryOrientation to QScreen::primaryOrientation() on the QWindow
level, as it leads to a lot of complexity regarding the
QWindow::contentOrientationChanged() signal, and makes it hard to
distinguish between the case where the window's orientation follows
that of the screen, and the case where the orientation just happens to
be set to that of the screen.
