Deprecate QApplication::setActiveWindow() and mark as internal

The function is used the internal window activation machinery and
should not be called by user code.

Many tests still use this function, and should be ported over to
QWidget::activateWindow(). For now they are using the private
helper in QApplicationPrivate, so that we can progress with the
public API deprecation.
