Simplifying options popup and overview handling
> Removing support for page drag-n-drop from pagedView
> Removing Overview UI from Launcher3 without quickstep and using options popup instead
> Removing touch handlers from CellLayouts and showing options popup based on workspace long press
> Excluding touch outside inset when showing the popup
