Add Accelerator Interface to GPU Sensors

This commit adds the xyz.openbmc_project.Inventory.Item.Accelerator
interface to IPMI GPU functional sensors.

This was something done earlier by commit
f510f7b6b708b22db1f08faf369994f01edd0ddc.
The same is being ported now to the new sensor config YAML.

Tested:
Loaded this change up on a witherspoon. Verified that the
inventory objects created by host-ipmid now implement the
xyz.openbmc_project.Inventory.Item.Accelerator interface.

busctl call xyz.openbmc_project.ObjectMapper /xyz/openbmc_project/object_mapper
xyz.openbmc_project.ObjectMapper GetSubTree sias
"/xyz/openbmc_project/inventory" 0 1
"xyz.openbmc_project.Inventory.Item.Accelerator"
a{sa{sas}} 6
"/xyz/openbmc_project/inventory/system/chassis/motherboard/gv100card0"
....
