patch 9.2.0468: popups: not correctly updated from a CmdlineChanged autocommand

Problem: popup_show() from a CmdlineChanged autocommand doesn't update
the screen (Mao-Yining)
Solution: Refresh the screen when popups need redraw
(Yasuhiro Matsumoto).

popup_settext()/popup_show() called from a CmdlineChanged autocommand
did not refresh the screen because cmdline mode normally skips
update_screen(), so async info-popup updates only became visible after
a manual :redraw. Refresh the screen when popups need redrawing right
after the autocommand.

fixes: #20175
closes: #20179
