Utility class can be 'enum'

Reports utility classes that can be converted to enums.

Some coding style guidelines require implementing utility classes as enums to avoid code coverage issues in private constructors.

Example:

class StringUtils {
  public static final String EMPTY = "";
}

After the quick-fix is applied:

enum StringUtils {
  ;
  public static final String EMPTY = "";
}
