refactor: remove unused private shim modules

Delete unused private re-export modules:
- _config.py (not used internally)
- _version_cls.py (not used internally)
- _cli.py (not used internally)

Update imports and entrypoints to use vcs_versioning directly:
- Update console_scripts entrypoint to vcs_versioning._cli:main
- Update test imports to use vcs_versioning modules
- __init__.py already imports directly from vcs_versioning

Keep modules that are still needed:
- _get_version_impl.py (has setuptools-specific get_version wrapper)
- _log.py (used internally by _integration and _file_finders)
- Public modules (version.py, integration.py, etc.) for backward compat
