android: camera_device: Queue request using Worker

Add a CameraWorker class member to the CameraDevice class and
queue capture requests to it to delegate its handling. Start and
stop the CameraWorker when the libcamera::Camera is started or
stopped.

Tie the CaptureRequest lifetime to the Camera3RequestDescriptor's one
by storing it as unique_ptr<> in the descriptor to simplify handling
of request creation and deletion.
