Subject: Fix "Wayland: crash with set_menu_window()" (#892)

Fixes also a similar crash occuring after use of set_tooltip_window().
Two bool member variables are added to class Fl_Window_Driver
to indicate true FLTK menu windows (i.e., created by Fl_Menu_Item::pulldown())
and true FLTK tooltip windows (i.e., Fl_Tooltip).
