gpu : add entity-manager support
The commit add support for reading of the entity-manager configurations
to the gpu dbus sensor app.
Tested.
Build an image for gb200nvl-obmc machine with the following patches
cherry picked. This patches are needed to enable the mctp stack.
https://gerrit.openbmc.org/c/openbmc/openbmc/+/79312
https://gerrit.openbmc.org/c/openbmc/openbmc/+/79410
https://gerrit.openbmc.org/c/openbmc/openbmc/+/79422
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
```
Copy the gpusensor app and run it.
```
root@gb200nvl-obmc:~# ./gpusensor
```
The app is detecting entity-manager configuration on gb200nvl-obmc
machine. The app is also able to detect all the endpoints from the mctp
service dbus tree.
