### What this PR does / why we need it?
This PR builds upon PR #5011 and aims to further enhance the
npu_graph_ex_passes module. Based on prior work, we have added graph
optimization support for the add_rms_quant fused operator in scenarios
where a bias term is present—ensuring the fusion pattern is correctly
registered and matched into the computation graph.
For validation, we switched to the Qwen3-235B-A22B-W8A8 model. Benchmark
results show that, compared to the unfused baseline, enabling this
fusion pass significantly improves inference throughput for W8A8
quantized models.
For more details can refer to the
RFC:https://github.com/vllm-project/vllm-ascend/issues/4715
