Enum deprecated syntax detection implemented and integrated into DeclarationsChecker.

A lot of tests was changed to refactor deprecated syntax. Six new tests were added to check deprecated syntax detection.
Diagnostic for "enum entry uses deprecated super constructor": constructor is highlighted
Diagnostic for "enum entry uses deprecated or no delimiter".
One warning removed.
