patch 9.1.0709: GUIEnter event not found in Turkish locale
Problem: GUIEnter not found in Turkish locale
(James McCoy, after v9.1.0256, the issue was there before,
but v9.1.0256 made it more apparent)
Solution: explicitly compare autocommand events by ASCII value and
ignoring locale, because according to the documentation,
events are case insensitive (:h autocommand-events)
fixes: #15574
closes: #15603
