Search 6 groundwork - Restore support for search hit explanation

Description

In particular:

  • the explanation projection: org.hibernate.search.engine.ProjectionConstants#EXPLANATION (Done in HSEARCH‌-3086)

  • org.hibernate.search.jpa.FullTextQuery#explain

Regarding APIs, maybe this should just return an implementation-specific object (Explanation for Lucene, String or JsonObject for Elasticsearch, …). Or be handled through extensions.
