patch 9.1.1230: inconsistent CTRL-C behaviour for popup windows

Problem:  Ctrl-C closes popup windows that have a filter callback,
          but does not close popups without a filter callback.
Solution: Modified popup_do_filter() to also close popups without
          filter callback when Ctrl-C is pressed (glepnir).

fixes: #16839
closes: #16928
