#### Why I did it
To be ready for 202505 cutoff
Support for pipe mode in IPIP packets when decapped - request from NetScan. Current support is for all platforms except broadcom SKUs. SAI attribute `SAI_TUNNEL_ATTR_DECAP_QOS_DSCP_TO_TC_MAP` will be used since the `decap_dscp_to_tc_map` key is set in the template.

#### How I did it
#### How to verify it
Ran template change on a lab device.
```
# template
...
{% if "broadcom" in asic_type %}
"dscp_mode":"uniform",
{% else %}
"dscp_mode":"pipe",
"decap_dscp_to_tc_map":"AZURE",
...
# output
{
"TUNNEL_DECAP_TABLE:IPINIP_TUNNEL" : {
"tunnel_type":"IPINIP",
"dscp_mode":"uniform",
"ecn_mode":"copy_from_outer",
"ttl_mode":"pipe"
},
"OP": "SET"
},
