[gtk/abolish-size-allocate: 14/17] tooltip: Add private api to allocate the window

[Matthias Clasen <matthiasc src gnome org>]

    tooltip: Add private api to allocate the window
    
    Add private gtk_tooltip_maybe_allocate() function
    and use it from GtkWindow and GtkPopover.
    
    This will let us stop using the ::size-allocate signal,
    without having to redo all the tooltip management first.
    
    That will happen later.
