    For a given `NativeFunction`, find out the corresponding backend and dispatch to it. If more than one
    backends exsit, fallback to static dispatch by determining dispatch key from inputs.
    Arguments:
        sig: A CppSignature or DispatcherSignature for this native function we want to use.
        f: NativeFunction to generate static dispatch.
        backend_indices: All available backends.
    Return:
        C++ code to call backend-specific functions, e.g., "return at::cpu::add(self, other, scale);"

WARNING: The generated AOTInductor C shim header files have unexpectedly changed. This
indicates an AOTInductor fallback operator ABI backward compatibility breakage!!!
Only in a limited number of situations, this is allowed:

1. You added a fallback op to the inductor_fallback_ops list in torchgen/aoti/fallback_ops.py.
If that's the case, run `python torchgen/gen.py --update-aoti-c-shim` to update the existing
C shim header files.

2. You added a new default argument to an existing fallback op. This is clearly a BC breaking
change in the AOTInductor land. In this case, you need to keep a manual copy of that existing
fallback op in a file, e.g. torch/csrc/inductor/aoti_torch/c/shim.h, bump up the version
number of that fallback op in the newly generated C shim files, and update the cpp wrapper
codegen to generate the correct cpp call for this op. Contact AOTInductor team for assistance.
