RFR: 8338751: ConfigureNotify behavior has changed in KWin 6.2

[Vlad Zahorodnii]

Prior to 6.2, kwin used to always send synthetic ConfigureNotify events regardless whether a real ConfigureNotify event is going to be sent. It used to do it because of some bugs in GTK2.

In 6.2, that workaround was dropped (it was needed to fix other issues during interactive resize) so kwin adheres to ICCCM 4.1.5 now.

Unfortunately, it seems like JDK relies on kwin always sending synthetic configure notify events, which is no longer the case.

This change makes AWT use the TranslateCoordinates request when a real ConfigureNotify event is received and running kwin as the window manager. It should work as expected even with kwin < 6.2.
