This is a prerequisite for #27209 : changing the interface in
OpenStorageTrie
to accept an address instead of an address hash. This interface change is needed for verkle trees, as the hashing algorithm used to find storage is not keccak.The problem this PR addresses, is that the node iterator would require preimage usage to conform to this new interface. Luckily, the node iterator is only used in tests, so this preimage requirement can easily be enforced. For this to happen, though, the node iterator interface should be unexported, lest someone else starts using it in the meantime.
