Fix test names for pytest

[justinchuby]

With the latest version of pytest we get

onnxscript/rewriter/ort_fusions/cos_sin_cache_test.py::test_case_1 - Failed: Expected None, but test returned <onnxscript.rewriter.ort_fusions.models._rotary_embedding_models._TestCase1 object at 0x117c920d0>. Did you mean to use assert instead of return?

This is because the imported functions test_case_1 and test_case_2 are not really test cases but were treated as such by pytest. This PR hides them from the test module so they are not triggered.

Pull Request Overview

This PR prevents pytest from discovering helper functions (test_case_1, test_case_2, etc.) as standalone test cases by switching from direct imports to module imports and updating all references accordingly.

• Replaced direct imports of test-case constructors with module-level imports for _rotary_embedding_models and _smollm_1
• Updated all usages to qualify test constructors with their module to hide them from pytest

onnxscript/rewriter/ort_fusions/cos_sin_cache_test.py:54

• [nitpick] Rename the variable test to something more descriptive (e.g., test_case or case) to avoid shadowing built-ins and clarify its purpose.

test = _rotary_embedding_models.partial_rotary_test_case()

onnxscript/rewriter/ort_fusions/cos_sin_cache_test.py:12

• [nitpick] Consider aliasing these module imports to shorter names (e.g., _rotary_embedding_models as rem_models, _smollm_1 as smollm_models) to reduce verbosity and improve readability in the test code.

from onnxscript.rewriter.ort_fusions.models import _rotary_embedding_models, _smollm_1

Looks like a bad naming. Maybe we should consider rename it.
