Summary FrameView::visibleSize() is unscaled on macOS, but scaled on iOS

FrameView::visibleSize() is inconsistent between macOS and iOS (WK2). On macOS, it boils down to ScrollView::unobscuredContentRectInternal() which adjusts for scale. On iOS, it just returns m_unobscuredContentSize which was set by the UI process, but not adjusted for page scale.

Seems that macOS is wrong. ScrollView::unobscuredContentRectInternal() should return a "content" rect. The rect it returns has a maxX/maxY that is larger than the document rect.
