Cleanup QCameraInfo

Various API changes to QCameraInfo:

* Remove the camera orientation from our API This is
an implementation detail that should never be exposed
to the user. For fixed cameras it's uninteresting
and for mobile cameras, we can use the physical orientation
of the device to create a stream that is oriented the
correct way.
* Add a QVideoFormat class describing a video format
* Add a QList<QVideoFormat> videoFormats()
* Add a QList<QSize> photoResolutions()
* Implement the API for gstreamer and macOS.
