The [UIApplication setStatusBarOrientation:animated] API has been deprecated since iOS 8, and a no-op since iOS 13. It is no longer possible to report the orientation of a view or view controller independently of the orientation of the view itself. This was problematic because we were applying additional logic to our screen geometry mapping based on the assumption that the API was still doing something, resulting in broken auto rotation when calling reportContentOrientationChange(). Removing the iOS implementation for reportContentOrientationChange makes this API a no-op on QWindow as well, as no other platforms seem to implement it. We should perhaps consider re-thinking the screen orientation APIs in this light. [ChangeLog][iOS] QWindow::reportContentOrientationChange no longer has any effect on iOS, as the APIs used to implement this on iOS are no longer available.
