android: camera_stream: Retrieve Stream and Configuration

Browse source 
It's a common pattern to access the libcamera::Stream and
libcamera::StreamConfiguration using the CameraStream instance's
index.

Add two methods to the CameraStream to shorten access to the
two fields. This allows removing the index() method from the class
interface.
