### What this PR does / why we need it?
1. now, npu_model_runner reuses gpu_model_runner, this pr deletes some
attrs already defined in gpu_model_runner
2. fix mtp accept rate by disabling in_profile_run
3. remove redundant moe method selection logic
4. Reverts vllm-project/vllm-ascend#5082, which broke CI in
https://github.com/vllm-project/vllm-ascend/actions/runs/20266314048/job/58190426832?pr=5088
