DevTools: Refactoring UI Elements

Moving UI specific methods from UI Element to either Window, View
or Widget. Once we create common UIElement for UI and Viz it'll be
easier to follow changes since this refactor is done. Common
UIElement will not know about the functions moved in this CL, so I
think it's better to do this now.
