Motivation

State cache handling is a very sensitive part of Lodestar and should be handled with care. Exposing the state cache data structure directly encourages assumptions about which state may or may not be available. IMO consumers should always go through regen as the ultimate provider of any state under some constraints (sync only, allow replay, etc)

NOTE: there's no change of logic**, just added enough new methods to map 1:1 current unstable

Description

Make state caches data structure internal to regen only
