chore: add BatchNorm operator in compile_torch tests

[RomanBredehoft]

We should make sure to test the torch operators that we claim supporting, but maybe there's a better place where to do so (or have a dedicated test ?), so feel free to share your opinion on it

⚠️ Known flaky tests have been re-run ⚠️

One or several tests initially failed but were detected as known flaky tests. They therefore have been re-run and passed. See below for more details.

Failed tests details

Known flaky tests that initially failed:

• tests/torch/test_compile_torch.py::test_compile_torch_or_onnx_conv_networks[True-True-CNN-relu]- tests/torch/test_compile_torch.py::test_compile_torch_or_onnx_conv_networks[True-True-CNN_grouped-relu]
