Introduce nativeOrientation() to QPlatformScreen
Now QPlatformScreen has a nativeOrientation() method which default
implementation return Qt::PrimaryOrientation. Its purpose is to return
the native orientation of the device (e.g. when the device logo is right
up).
Only the QPA backend can know for sure what this native orientation is,
so allow QPA backends to override it with a finer result.
