libcamera: properties: Provide a Devices camera property
Provide a new Camera property that allows pipeline handlers to list any
kernel device used to operate the camera. This allows other frameworks
and daemons such as PipeWire to better understand the resources consumed
by a Camera and consider ignoring those resources when enumerating
camera devices on a system.
