android: camera_device: Replace running_ with CameraState

The CameraDevice class maintains the camera state in the 'running_'
boolean flag to check if the camera has to be started at the first
received process_capture_request() call which happens after the camera
had been stopped.

So far this was correct, as the operations that change the camera
could only start or stop the camera, so a simple boolean flag
was enough.

To prepare to handle the flush() operation that will introduce a new
'flushing' state, replace the simple plain boolean flag with an
enumeration of values that define the CameraState.
