fix test_functional_call_sequential_params_and_buffers expectation on Windows (#134394)
Summary:
This UT actual code only one empty line wrap difference(`linear` and `add`) between Windows/Linux, and the context is right.
Reproduce UTs:
```cmd
pytest test\dynamo\test_higher_order_ops.py -v -k test_functional_call_sequential_params_and_buffers
```
We can add `empty_line_normalizer` to fix it.
```cmd
