Port away from KDeclarative::ConfigPropertyMap where possible

Because of the wallpaper interface from plasma-frameworks, we can not change
this during KF5. However we can use QQmlPropertyMap as the type, when we do not care
about the KConfig specific bits. Both KConfigPropertyMap and KDeclarative::ConfigPropertyMap
extend from this class.
