773d8074 - [ONNX] Clean up unit tests, rename files and improve import style (#81141)

[ONNX] Clean up unit tests, rename files and improve import style (#81141) - Rename `test_pytorch_common` -> `pytorch_test_common`, `test_onnx_common` -> `onnx_test_common`, removing the test_ prefix to show that the files are not test cases - Remove import * in `test_pytorch_common` and adjust to import from `testing._internal.common_utils` (where functions are actually defined) instead - Import modules only in `test_pytorch_onnx_onnxruntime` (too many to handle in a single PR in other tests) (The skips are exceptions) Pull Request resolved: https://github.com/pytorch/pytorch/pull/81141 Approved by: https://github.com/BowenBao
