Now that building the list of supported stream configuration requires
applying a configuration to the Camera, re-initialize the camera
controls by applying a configuration generated for the Viewfinder stream
role before building the list of static metadata.

Quite interestingly, we had no guarantee that the camera would be

And, had done by Javier in the other initialize*() functions I should
probably check for if (!cameraConfig).
