[Mellanox] Adjust buffer parameters with 2km cable supported for 4600…

…C 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) Signed-off-by: Stephen Sun <[email protected]>
