### What this PR does / why we need it? This PR revise the test cases of various features on the warehouse which add the enablement of aclgraph to the test cases. ### Does this PR introduce _any_ user-facing change? no ### How was this patch tested? ut - vLLM version: v0.11.0rc3 - vLLM main: https://github.com/vllm-project/vllm/commit/v0.11.0 Signed-off-by: lilinsiman <lilinsiman@gmail.com>
