style: Refactor the style checker as a Python package

Refactor the style checker into a Python module that can be reused by
command line tools that integrate with git. In particular:

  * Create a style package in util
  * Move style validators from style.py to the style/validators.py.
  * Move style verifiers from style.py to the style/verifiers.py.
  * Move utility functions (sort_includes, region handling,
    file_types) into the style package
  * Move generic code from style.py to style/style.py.
