### What this PR does / why we need it?
Fix 2 breaks of aclgraph with MTP:
1. deepseekmtp in vllm 0.11.0 does not support aclgraph and lack the
`support_torch_compile` decorator
2. There is a d2h synchornization in the original forward of mtp
predictor. The fix pr in vllm
https://github.com/vllm-project/vllm/pull/27643
As we'll fix it in vllm main, this fix pr is only needed in branch
v0.11.0-dev
The profling shows that MTP replays in aclgraph now:
