We have some builders, specifically query builders, `SearchSourceBuilder`, `QuerySourceBuilder` and `SuggestBuilder`, that implement `ToXContent` and also allow to build their content as bytes by simply creating a `BytesReference` that holds their json (or yaml etc.) content (`buildAsBytes` methods). They can also print out their content through `toString`. Made sure that those common methods are in one single place and reused where needed. Also, merged `QueryBuilder` and `BaseQueryBuilder` and made `QueryBuilder` an abstract class instead of an interface. Closes #11063
