Add support for EntityGraph

[pstrumni]

I'm using spring-data-jpa with Hibernate. When I've added EntityGraph annotation to repository method and run code I got exception:

java.lang.IllegalArgumentException: The EntityGraph-Feature requires at least a JPA 2.1 persistence provider!

I've checked implementation of org.springframework.data.jpa.repository.query.Jpa21Utils and find out that it throws this exception, because after aot compilation javax.persistence.NamedEntityGraph is not present.

Everything works with additional TypeHint:
@TypeHint(types = NamedEntityGraph.class)

I think it should work out-of-the-box without additional configuration. Could you fix it?

Thank you for the report!
