4750f745 - [ONNX] Disable parallel run for custom op related tests in CI (#78944)

[ONNX] Disable parallel run for custom op related tests in CI (#78944) Should fix #78844 Custom op related tests utilize inline cpp extension to build custom operator from c++ source snippet. Only two test cases become flaky after parallel run, and both use inline cpp extension. Reverting to run these tests in single process to try resolve the flakiness. Reverts test skip added previously #78936. Pull Request resolved: https://github.com/pytorch/pytorch/pull/78944 Approved by: https://github.com/janeyx99, https://github.com/garymm
