With ODATA-516 we introduced the abstract type Edm.AnyPath as an abstraction of Edm.AnnotationPath, Edm.PropertyPath, and Edm.NavigationPropertyPath.

We now face situations where we want to reference other types of model elements, e.g. bound actions or functions.

It seems wise to use the rather generic name "AnyPath" really for any path to any type of model element, which would
a) postpone the need for actually adding specific types Edm.ActionPath, Edm.FunctionPath, Edm.EntityTypePath, ...
b) allow us to later add these more specific types for the more common cases
