Move core configuration tests to vcs-versioning

Split setuptools-scm/testing_scm/test_config.py by moving core Configuration tests to vcs-versioning/testing_vcs/test_config.py.

Moved tests:
- test_tag_regex: tests Configuration tag_regex matching (core)
- test_config_regex_init: tests Configuration initialization with regex (core)
- test_config_bad_regex: tests Configuration validation (core)

Kept in setuptools-scm:
- test_config_from_pyproject: Configuration.from_file (setuptools integration)
- test_config_from_file_protects_relative_to: from_file warning (setuptools integration)
- test_config_overrides: from_file with env overrides (setuptools integration)

All tests pass: 407 passed, 10 skipped, 1 xfailed
