Stephen Sun 646a886a11 [Mellanox] Adjust buffer parameters with 2km cable supported for 4600C non-generic SKUs (#9215)
- Why I did it
Also recalculated all parameters with the latest algorithm with per-speed peer response time taken into account

- How I did it
Detailed information of each SKU:

C64:
t0: 32 100G downlinks and 32 100G uplinks
t1: 56 100G downlinks and 8 100G uplinks with 2km-cable supported
D112C8: 112 50G downlinks and 8 100G uplinks.
D48C40: 48 50G downlinks, 32 100G downlinks, and 8 100G uplinks
D100C12S2: 4 100G downlinks, 2 10G downlinks, 100 50G downlinks, and 8 100G uplinks
2km cable is supported for C64 on t1 only

- How to verify it
Run regression test (QoS)
