0028047: Visualization - support objects with customized highlighting in AIS_InteractiveContext

- SelectMgr_SelectableObject::ClearHighlighted method is added to remove dynamic highlight data;
- interactive context will pass processing of dynamic highlight erase to the object if the owner returns false in SelectMgr_EntityOwner::IsAutoHilight;
- if owner returns true in SelectMgr_EntityOwner::IsForcedHilight, selection presentation will be re-highlighted at each ::Select call;
- redundant logic related to old object-oriented highlight mechanism was removed from AIS_InteractiveContext::MoveTo.
