With fission it's not possible to use nsPIDOMWindowOuter::GetInProcessTop and expect to find the top-level window, since it might be in another process. Instead we use BrowsingContext::Top. Another issue is that it's not possible to traverse children by recursively calling GetTabSizes, instead we need to use BrowsingContext traversal mechanics. Memory reporting is a bit tricky, since now doc gropus belonging to a cross process top level browsing context needs to report it's memory usage and can't skip it, so this is also handled.
