video: Allow setting the parents of toplevel windows 

Allow setting a parent/child relationship on toplevel windows, which allows raising sets of windows together, and allows child windows to always float above their parents.

Modal windows are now set by setting the parent, then toggling modal status, as the previous interface duplicated functionality now handled by SDL_SetWindowParent().
