Alpesh Patel 6b48346ff5 qos template change for backend compute-ai deployment (#16150) 
#### Why I did it

To enable qos config for a certain backend deployment mode, for resource-type "Compute-AI".
This deployment has the following requirement:

- Config below enabled if DEVICE_TYPE as one of backend_device_types
- Config below enabled if ResourceType is 'Compute-AI'
- 2 lossless TCs' (2, 3)
- 2 lossy TCs' (0,1)
- DSCP to TC map uses 4 DSCP code points and maps to the TCs' as follows:
   "DSCP_TO_TC_MAP": {
        "AZURE": {
             "48" : "0",
            "46" : "1",
            "3"  : "3",
            "4"  : "4"
        }
    }

- WRED profile has green {min/max/mark%} as {2M/10M/5%}

This required template change <as in the PR> in addition to the vendor qos.json.j2 file (not included here).

### How I did it

#### How to verify it
- with the above change and the vendor config change, generated the qos.json file and verified that the objective stated in "Why I did it" was met

- verified no error

### Description for the changelog
Update qos_config.j2 for Comptue-AI deployment on one of backend device type roles
