Move PropertyPath and TypeInformation types to core package.

Our domain types Sort and ExampleMatcher were designed to use property paths forming a conceptual cycle between the mapping and domain package.

By moving PropertyPath support and related types (TypeInformation, wrapper and collection infrastructure) into a newly created core package we're resolving the design cycles resulting in an improved design reflecting the actual intended dependencies.

Types moved from org.springframework.data.mapping to org.springframework.data.core:

* PropertyPath
* PropertyReferenceException

Types moved from org.springframework.data.util to org.springframework.data.core:

* CustomCollections and CustomCollectionRegistrar
* NullableWrapper
* NullableWrapperConverters
* ReactiveWrappers
* TypeInformation

Closes #3393
