af04ee9e7a [MoE][Dist] Fix Qwen MoE accuracy bug in DP scenario (#1856)
### What this PR does / why we need it?
Fix Qwen MoE accuracy bug in DP scenario.

Now the implentment of `FusedMoE` in vLLM use `All2AllManager` to
manager different all2all algorithm branch. And the default branch use
`Multicast` in `dispatch` phase and `all_reduce` in `combine` phase,
which are not implented in vLLM-Ascend. This leading to invoking into a
default implentment in `base_communicator`, with empty `dispatch` and
`combine` operations, thus causing the accuracy issue on it.

This pr is a temporary workaround, refacting all2all in vLLM-Ascend
could be a better way.
