libcamera: device_enumerator: Move lookupDeviceNode() to child classes

The lookupDeviceNode() method is declared as pure virtual in the base
DeviceEnumerator class, but is only called by derived classes. Move it
to the DeviceEnumeratorSysfs and DeviceEnumeratorUdev. This allows
changing the udev version to take a dev_t instead of separate
major/minor, as that's what both the caller and the callee end up using.
