configurations: Add Nvidia MCTP VDM

DBus Sensor app for GPU Temperature Sensor will use this configuration.

Tested:

Copy the configuration file on gb200nvl-obmc machine and restart the
entity-manager service.

```
root@gb200nvl-obmc:~# rm -rf /var/configuration/
root@gb200nvl-obmc:~# systemctl restart xyz.openbmc_project.EntityManager.service
```

Inventory is properly detected on gb200nvl-obmc machine.
