[feature/dataflow] Handling of reflection on properties with regard to annotations

Using the annotations if somebody asks for properties on a type via `DynamicallyAccessedMemberKind.Properties` we would include both getter and setter on each property as that's the only sensible thing to do (getting the property alone is typically not useful, either getter or setter will be called on it later on). On the other hand linker tracks getters and setters separately, and so accessing the getter/setter (via `PropertyInfo.GetMethod` for example) will raise a warning as it can be potentially trimmed. Linker won't be able to figure out that the `PropertyInfo` comes from a type which had all properties included and thus both getter/setter are available.

This basically means that the annotations will help with calls to `Type.GetProperty`, but won't help with calls to `PropertyInfo.GetMethod` - those wills till raise warnings.
