android: camera_device: Support MJPEG stream construction

MJPEG streams must be created referencing a libcamera stream.
This stream may already be provided by the request configuration,
in which case the existing stream is utilised.

If no compatible stream is available to encode, a new stream is requested
from the libcamera configuration.
