core/state: replace writing TrieJournal to the database with a journal file

[jingjunLi]

Description

When the traffic is high, and BSC shuts down, the PBSS's TrieJournal becomes a large key-value pair (over 2GB), which can cause bugs in Pebble. To address this issue, we use a journal log file to store the TrieJournal instead of persisting it to the database.
