AEC Data Model API: new field revitElementId in ElementAlternativeIdentifiers and ElementFilterInput

This field is supported by both standard and advanced filtering options including ElementAlternativeIdentifiers and ElementFilterInput. The revitElementId is now the preferred method for retrieving elements.
