Fix sixtyfps::quit_event_loop() not exiting the event loop with Qt 6 on macOS

Browse source 
As per commit 0c02f133f3daee146b805149e69bba8cee6727b2 in qtbase (qt6),
quit() on QCoreApplication on macOS calls [NSApp terminate], which will
not return to main. The latter however is documented behavior, and
sixtyfps-viewer for example relies on it.
