QGuiApplication::focusObject() to replace QInputPanel::inputItem()

* Deprecated QInputPanel::inputWindow() which is already
  just returning QGuiApplication::activeWindow()
* Deprecated QInputPanel::inputItem() and introduced
  QGuiApplication::focusObject(). Input methods can check
  input method support by Qt::ImEnabled query.
