Move _c_api_utils.py to version_converter package

[Copilot]

This PR moves _c_api_utils.py from onnxscript/ir/passes/common/ to onnxscript/version_converter/ since it's only used by the version converter module.

Changes

• Moved onnxscript/ir/passes/common/_c_api_utils.py to onnxscript/version_converter/_c_api_utils.py
• Updated import in onnxscript/version_converter/__init__.py from from onnxscript.ir.passes.common import _c_api_utils to from . import _c_api_utils

Analysis

A codebase analysis confirmed that _c_api_utils.py is only imported and used by the version converter:

• The file contains utilities for interfacing with ONNX C APIs, specifically the call_onnx_api function
• It's only imported in onnxscript/version_converter/__init__.py
• It's not exported in any __all__ lists
• No other modules reference or use this utility

Moving the file to the version converter package improves code organization by colocating the utility with its sole consumer.

Fixes #2400.
