Add support for factory methods.

Browse Source 
R2DBC now supports the use of factory methods for entity creation.
Spring Data JDBC already does so via f326897950

Simply annotate a static factory method on your entity class with `@PersistenceCreator`.

Closes #1346
See https://github.com/spring-projects/spring-data-commons/issues/2476
See f326897950
