Motivation and Context

With the new Property Wrappers in Swift 5.1 we can improve our ServiceLocator feature. This PR proposes an approach for such a property wrapper.

Description

I've added the new properly wrapper. To test I am thinking about creating a Mock class with a property annotated with this wrapper. Then I can register services in Test Methods and test that this Mock Class can be properly instantiated.
