QSystemTrayIcon: Allow resetting context menu

Browse Source 
Fix logic in QSystemTrayIconPrivate::updateMenu_sys() to allow resetting
the tray icon menu. Now we correctly handle `nullptr` menu, and update
the underlying QPlatformSystemTrayIcon instance accordingly.

Also we bail out from QSystemTrayIcon::setContextMenu() early if the
menu is the same.

Fixes: QTBUG-119068
Pick-to: 6.5
