[hotfix] moe hybrid parallelism benchmark & follow-up fix (#6048)

* [example] pass use_fp8_comm flag to all plugins

* [example] add mixtral benchmark

* [moe] refine assertion and check

* [moe] fix mixtral & add more tests

* [moe] consider checking dp * sp group and moe_dp_group

* [mixtral] remove gate tp & add more tests

* [deepseek] fix tp & sp for deepseek

* [mixtral] minor fix

* [deepseek] add deepseek benchmark
