  [libpng16] style: Add a cmake-format config file and satisfy cmake-lint
  
  Introduce CMake file linting, based on the cmakelang project by
  Josh Bialkowski (@cheshirekow).
  
  Fix various style issues in the CMake files:
   * Add the missing copyright header to PNGConfig.cmake.
   * Resolve a "missing docstring" warning raised by cmake-lint.
   * Rewrite all docstrings in the style of CMake's own documentation.
   * Fix whitespace inconsistencies.
  
  References:
   * https://pypi.org/project/cmakelang
   * https://github.com/cheshirekow/cmake_format
  
  This is a cherry-pick of commit c317fe31114d92d05d44bf98c9b559edf4656b9c
  from branch 'libpng18'.
