ed48ea9997 [AOTI] Refine the C shim autogen mechanism (#125589)
Summary: Based on the discussions in https://github.com/pytorch/pytorch/pull/120513. Instead of auto-generate C shim fallback ops for thousands of ops, we maintain a list of fallback ops based on torch/_inductor/lowering.py, and only generate C shim functions for those ops. At the torchgen time, we will re-generate C shim files and compare the header file contents against the existing C shim headers. If there is any change, the compilation will fail with prompt on how to proceed. This makes sure the ABI-compatible C shim layer is small enough to maintain in the long run.
