libcamera: pipeline: Register device numbers with camera

Browse source 
Register the identified device numbers with each camera as the
SystemDevices property.

This facilitates camera daemons or other systems to identify which
devices are being managed by libcamera, and can prevent duplication of
camera resources.

As the SystemDevices property now provides this list of devices, use it
directly from within the CameraManager when adding a Camera rather than
passing it through the internal API.
