The main intention of this change is to have a consistent look and behavior across all scrollbars, including elements with `overflow: scroll` and `overflow: auto`, iframes, and a page. Before: - Page's scrollbar is painted by Browser (Qt/AppKit) using the corresponding UI framework style, - Both WebContent and Browser know the scroll position offset. - WebContent uses did_request_scroll_to() IPC call to send updates. - Browser uses set_viewport_rect() to send updates. After: - Page's scrollbar is painted on WebContent side using the same style as currently used for elements with `overflow: scroll` and `overflow: auto`. A nice side effects: scrollbars are now painted for iframes, and page's scrollbar respects scrollbar-width CSS property. - Only WebContent knows scroll position offset. - did_request_scroll_to() is no longer used. - set_viewport_rect() is changed to set_viewport_size().
