0029724: Visualization - add AIS_InteractiveContext::ClearDetected() undoing MoveTo() dynamic highlighting

Introduced new method AIS_InteractiveContext::ClearDetected() allowing
to reset the list of detected objects and clear dynamically highlighted
entity under mouse cursor after previous AIS_InteractiveContext::MoveTo().

vmoveto command has been extended with new argument -reset.
