android: camera_device: Refuse unsupported formats

The current implementation of CameraDevice::initializeStreamConfigurations()
fails if an image format marked as mandatory is not supported by the
libcamera::Camera device, but erroneously accepts non-mandatory
non-supported formats in the list of accepted ones.

Fix this by ignoring non supported image formats which are not marked as
mandatory.
