[ONNX] Add pass that fuses Conv and BatchNormalization (#40547)
Summary:
Add pass that fuses Conv and Batchnormalization nodes into one node Conv.
This pass is only applied in inference mode (training is None or TrainingMode.Eval).
Since this pass needs access to param_dict it is written outside peephole file where these kind of passes (fusing multiple nodes into one) is usually placed.
This PR also adds wrapper skipIfNoEmbed to skip debug_embed_params test:
Pass that fuses Conv and Batchnorm changes the params of resnet model and parameters of onnx and pytorch model won't match. Since parameters are not matching, debug_embed_params test for test_resnet will fail and that is expected, therefore debug_embed_params test for test_resnet should be skipped.
