Subject: libcamera: camera_manager: Move private implementation to internal

The CameraManager makes use of the Extensible pattern to provide an
internal private implementation that is not exposed in the public API.

Move the Private declaration to an internal header to make it available
from other internal components in preperation for reducing the surface
area of the public interface of the CameraManager.
