Remove QScreen::orientationUpdateMask

It simplifies the API and reduces surprise to have rotation working by default.
On Android, the manifest specifies which orientations the application has
been designed to support; on iOS, it is controlled via the
UISupportedInterfaceOrientations property list key.
In addition, QWindow::contentOrientation() is another way to give
a hint to the window manager, or on iOS to directly control whether
the window's rotation is locked or not.

-    Reimplement this function in subclass to filter out unneeded screen
-    orientation updates.
-
-    The orientations will anyway be filtered before QScreen::orientationChanged()
-    is emitted, but the mask can be used by the platform plugin for example to
-    prevent having to have an accelerometer sensor running all the time, or to
-    improve the reported values. As an example of the latter, in case of only
-    Landscape | InvertedLandscape being set in the mask, on a platform that gets
-    its orientation readings from an accelerometer sensor embedded in a handheld
-    device, the platform can report transitions between the two even when the
-    device is held in an orientation that's closer to portrait.
-
-    By default, the orientation update mask is empty, so unless this function
-    has been called with a non-empty mask the platform does not need to report
-    any orientation updates through
-    QWindowSystemInterface::handleScreenOrientationChange().
