[JIT] log extract tool - dump NVFuser fallbacks instead of fusion groups (#73881)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/73881
NVFuser fusion groups can contain nvfuser-only ops, e.g. `prim::reshape_copy`. Previously, we couldn't get a baseline performance measurement because the nvfuser-only ops would error out on nnc- and no-fusion- runs. Instead, dump the fallback graphs, after the fallbacks are corrected into runnable fallbacks.
