window: Introduce meta_window_get_tile_match()

Returns the matching tiled window. This is the topmost tiled window in a
complementary tile mode that is:

 - on the same monitor;
 - on the same workspace;
 - spanning the remaining monitor width;
 - there is no 3rd window stacked between both tiled windows that's
   partially visible in the common edge.
