        DocumentMaker::AllMarkers should not be a part of DocumentMarker::MarkerType
        https://bugs.webkit.org/show_bug.cgi?id=58112

        - Converted DocumentMarker::MarkerTypes from unsigned int to a class.
        - Converted DocumentMarker::AllMarkers from an enum entry to a subclass of MarkerTypes.
        - Changed type of some MarkerType argument on DocumentMarkerController API to MarkerTypes
          which should allow a combination of MarkerType constansts.
        - Removed some MarkerType arguments on DocumentMarkerController API
          which only received AllMarkers.

        No new tests, no behavior change.
