#### Why I did it
This is a manual cherry-pick of
sonic-net#24289
Upgrade the xgs SAI version to 13.2.1.10 to include the following
changes:
- OCP SAI spec Version upgrade from 1.16.3 -> 1.16.4
- TH_Regular : Memory leak is observed during warm shut and cold shut
during warm boot.
- Uplift SDKLT-51968 to 13.2.1: Drop counter is increasing even if port
is Oper down
- On TH4GT: Need to disable TunnelMpIp4ip6 tests as per Jira
SONIC-108933
- Updated PORT attribute PRIORITY_FLOW_CONTROL handling for TH5 with a
custom value 2 for config property sai_pfc_dlr_init_capability
##### Work item tracking
- Microsoft ADO **(number only)**: 35635641
