Sherlock Huang cf2de4e230 Introduce aoti_call_delegate HOP (#145630)
Summary:
Previously, aoti compile node is represented as a kernel-less custom op in the exported program. The node was not eager runnable, which is a common practice for numerical validation during lowering.

I introduce a new HOP to address this.

The schema is following
```
aoti_call_delegate(lower_moduel: AOTInductorEPModule, original_gm: fx.GraphModule, weights: List[Tensor], inputs: List[Tensor])
```

There are a few problems exposed by HOP
- AOTI expects a FX graph with weights as getattr nodes, aka stateful graph. HOP expect graph_module arguments to be stateless. Export serializer also expect a stateless graph. Currently, to make AOTI happy, I am making `original_gm` stateful, and bypassing the serialization for `original_gm`.
- As a result, the HOP is not re-traceable, as functionalization on stateful graph module argument will fail.

Test Plan: buck2 test 'fbcode//mode/opt' fbcode//deeplearning/aot_inductor/cpu/test:cpu_lowering_utils_test
