android: camera_stream: Add sourceStream

Add a sourceStream field to the CameraStream class, meant to contain a reference to the direct stream which produces actual image data for streams of type CameraStream::Mapped. The sourceStream of mapped streams will be used in later patches to make sure for each Mapped stream at least one libcamera::Stream is queued to the libcamera::Camera.
