All of the users of get_input_rect don't actually want a synthesized input rect based off of the current margins. What they really want is the last-configured size of the toplevel window. Since we don't properly track this anymore in the generic MetaWindow, use XGetWindowAttributes to fetch a server-side rectangle. This is a bad layer violation, but since the window geometry code will have to be rewritten anyway for the Wayland set_window_geometry, let's just push a hacky fix for now.
