Remove FindPersistenceMethod

This commit removes FindPersistenceMethod and FindAllPersistenceMethod
and moves the logic to shared code for both Hibernate and Hibernate. In
order to achieve this a new AbstractHibernateGormStaticApi is
introduced in the ‘grails-datastore-gorm-hibernate-core’ submodule that
implements the necessary logic for the findAll and find methods that
accept String-based queries
