As of Qt 6 (3e12951c0b35041920989d6089ddb6c2f5c2d3d1, the QScreen's orientation() property is supposed to represent the orientation of the screen from a window management perspective, and not the orientation of the actual device, as in Qt 5 times. For iOS, when the orientation of the app is locked to a orientation via the Info.plist or [UIViewController supportedInterfaceOrientations], the UIDevice API will keep reporting the actual orientation of the device, which is wrong for the Qt 6 definition of the API. We currently don't have an API in QScreen to represent the always updating physical rotation of the device. For this use-case the supported API is QOrientationReading in Qt Sensors. [ChangeLog][iOS] QScreen::orientation() will no longer report the device's physical orientation when orientation has been locked to a subset of the available orientations, but will instead match the primary orientation.
