[Storehouse] 008 Replay WAL onto Payloadless trie

[zhangchiqing]

The previous PR #8578 defines a checkpoint, and can start up the node with a v7 checkpoint.

This PR adds the white ahead logs (WAL) replaying for payloadless trie so that on startup, after loading a payloadless checkpoint file, it can continue replaying the WAL files deriving the trie for the last executed block and resume the execution.

Pre-existing, but the read loop below checks reader.Err() only inside the loop. reader.Next() returns false on both clean EOF and read error, so if the final Next() returns false due to a corrupt/truncated record, reader.Err() is non-nil but never checked.
