android: camera_device: Maintain a vector of CameraStream

Browse source 
Introduce a vector storing a CameraStream to track and maintain
state between an Android stream (camera3_stream_t) and a libcamera
Stream.

Only the index of the libcamera stream is stored, to facilitate identifying
the correct index for both the StreamConfiguration and Stream vectors.
