Complicated ops are not well-covered by extra_opinfo

[titaiwangms]

For example, #1271. In FFT family, we are not relying on torch op tests from PyTorch, so in some complicated ops, such as FFTs, layer_norm, upsampling, etc.., are passing tests in onnxscript, but failing in torch ops test. To avoid back and forth fixing the ops, we should have test_fx_op_consistency to enable integration tests in onnxscript for these complicated ops.
