feature_select: Implement True Properties

This feature is now almost fully implemented.

TODO: Static properties like `QtWidgets.QApplication.platformName` are
      skipped for now. They need support by the meta class.
      Maybe this is a reason to use QtCore.Property instead of vanilla
      Python property and improve it.

With the new infrastructure, we can also consider to add properties
which have no equivalent in the Qt implementation. A prominent
example is "central_widget".
