feat(database): Implement DatabaseRef for State

[cakevm]

Fixes #2566, implementing DatabaseRef for State.

The ref db implementation does not write to the cache, it tries to read from the cache, then optional from bundle state, and if both fails from the database. For the storage_ref I am not 100% sure if I got the account status check right and if bundle state is correctly used here.
