make refs executor handle kwargs (#79858)
Mostly fixes #78923
I had to disable function patching in fx for functions with kwonly args, see https://github.com/pytorch/pytorch/compare/ngimel/make_fx_fix?expand=1#diff-090b22122be0779cd14afd2ebaf20d1e7c0bfe837e9eefa1d84e7521bb1defc6R446, cc @jamesr66a
But it looks like it was doing weird things anyway - it was patching signature of wrapped function with arbitrary local vars from wrapper, that can't be right, but I don't know what the intent there is.
A lot of functions now fail with nvfuser executor, and some still fail with aten, although with the different errors than before.
Edit: undid the change to _symbolic_script.py, turns out inspect.unwrapping function is not needed, and fx never sees kwargs.
