[CORE][DB][ENTITY][Actor] Make DB::dql return a chunked array if selecting multiple entities, remove partitioning from callsite
`DB::dql('select a, b, from a join b')` would previously return `[a,
b, a, b, ...]` (or even `[b, a, b, a, ...]`), and now will return
`[[a, a, ...], [b, b, ...]]`. The issue would be further compounded
when selecting even more entities, where the order would be
unpredictable
