[Mellanox] Support buffer configuration for 2km cables (#7337)
#### Why I did it
Support 2km cables for Microsoft SKUs

#### How I did it
1. Update pg_profile_lookup.ini with 2000m cable supported
2. Update buffer configuration for t1 with uplink cable 2000m
  - For SN3800 platform:
    - C64:
      - t0: 32 100G down links and 32 100G up links.
      - t1: 56 100G down links and 8 100G up links with 2 km cable.
    - D112C8: 112 50G down links and 8 100G up links.
    - D24C52: 24 50G down links, 20 100G down links, and 32 100G up links.
    - D28C50: 28 50G down links, 18 100G down links, and 32 100G up links.
  - For SN2700 platform:
    - D48C8: 48 50G down links and 8 100G up links.
    - C32:
      - t0: 16 100G down links and 16 100G up links.
      - t1: 24 100G down links and 8 100G up links with 2 km cable.
  - For SN4600C platform:
    - D112C8: 112 50G down links and 8 100G up links.

#### How to verify it
Run regression test
