xcb: Don't send "Qt::WindowNoState" event when hiding minimized window
This prevents getting "QWidget::showEvent()" when hiding minimized
widget on some WMs like Marco or Xfwm4.
If QWindow is minimized and it gets the new "XCB_WM_STATE_WITHDRAWN"
event from XCB, then don't change the QWindow state.
Task-number: QTBUG-55942
