Added an interface check here, but I didn't define ledger.PayloadlessLedger interface for payloadless ledger struct yet, will add in future PR.

The full ledger's Prove returns ledger.Proof which is a []byte slice, which is encoded trie.
However, we return a structured data *ledger.PayloadlessTrieBatchProof for now instead of []byte, because the caller will need to assemble with the payload value, and also read the leaf hash to verify the payload value. In the future, it can be optimized to []byte to reduce some decoding work.

Is this missing an error doc. I think this can return "no trie is stored in the forest". Same for MostRecentTouchedState.

nit: The doc string is missing the expected errors.
