[SWDEV-463402] - Support retrieving connection type and P2P capabilities between two GPUs

Browse Source 
1. Add a API interface amdsmi_topo_get_p2p_status to retrieve
connection type and P2P capabilities between 2 GPUs.

2. Add getting p2p status test in hw_topology_read
to print P2P capability information.

3. Add below tables for cli topology sub commands:
  - CACHE COHERANCY TABLE
  - ATOMICS TABLE
  - DMA TABLE
  - BI-DIRECTIONAL TABLE
