[ONNX] Enable _jit_pass_onnx_fold_if only when dynamic_axes is None (#50582) (#50910) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/50910 Fixing pytorch/vision#3251 (PR #49410 triggers the torch vision test build failure, on three tests test_faster_rcnn, test_mask_rcnn, test_keypoint_rcnn. ) The offending PR is fine on pytorch UT, because the torchvision and pytorch test has a gap when we merge them - we are using different test API on two sides, therefore causing some discrepancy. This PR bridge the gap for the above three tests, and disable _jit_pass_onnx_fold_if pass until it gets fixed. Allow _jit_pass_onnx_fold_if only when dynamic_axes is None.
