hwhaokun fb9fdcdbe4 [Feat] enable hierarchical mc2 ops on A2 by default (#5545) ...

### What this PR does / why we need it?
Previously, it was necessary to set the environment variables
HCCL_INTRA_PCIE_ENABLE=1 and HCCL_INTRA_ROCE_ENABLE=0. This PR enables
hierarchical MC2 operations on A2 by default.
### Does this PR introduce _any_ user-facing change?

### How was this patch tested?
