Made QWindow::currentOrientation() a property.

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.

This enum type specifies the various orientations a screen might have.
\value PrimaryOrientation The display's primary orientation. The QWindow and QScreen APIs never return this value,
instead it will be mapped to the corresponding QScreen's QScreen::primaryOrientation().
\value PrimaryOrientation The display's primary orientation.
\value LandscapeOrientation Landscape orientation, display width is greater than display height.
\value PortraitOrientation Portrait orientation, display height is greater than display width,
rotated 90 degree clockwise relative to landscape.
