Serialize a bank to a snapshot

DEVELOPER NOTE Any error that is returned from this function may bring down the node! This function is called from AccountsBackgroundService to handle snapshot requests. Since taking a snapshot is not permitted to fail, any errors returned here will trigger the node to shutdown. So, be careful whenever adding new code that may return errors.
