Helper class that provides setTarget() functionality for both value
interceptors and value sources.
Property value sources could be problematic because QQuickAbstractAnimation
changes access specifier of QQmlPropertyValueSource::setTarget() to private
(unintentionally?). This API allows to avoid manual casts to base types as
the C++ compiler would implicitly cast derived classes in this case.
