don't change a widget's active state in QWindowsWindow::setWindowState

Browse Source 
QWindow::setWindowState is not supposed to set the window active.
The method requestActivateWindow() should be used for that.

When switching from and to fullscreen mode we're always passing
SWP_NOACTIVATE to SetWindowPos to not change the activation state
of the window. This is inverse to the old behaviour, which did not
have an effect.
