### What this PR does / why we need it?
Currently, in the piecewise of aclgraph, the model will be in eagle mode
in attention, which will cause abnormal allreduce latency of O matrix.
The reason is that cpu resources will be preempted in eagle mode. So I
hope to temporarily add cpu binding to vllm-ascend.
