Add ability to switch between current blockchain storage and MPT-backed storage for iterator traversing process. It may be useful because iterator implementation traverses underlying backed storage (BoltDB, LevelDB) inside DB's Seek which is blocking operation for BoltDB: ``` Opening a read transaction and a write transaction in the same goroutine can cause the writer to deadlock because the database periodically needs to re-mmap itself as it grows and it cannot do that while a read transaction is open. If a long running read transaction (for example, a snapshot transaction) is needed, you might want to set DB.InitialMmapSize to a large enough value to avoid potential blocking of write transaction. ``` So during bbolt re-mmaping, standard blockchain DB operations (i.e. persist) can be blocked until iterator resourses release. The described behaviour is tested and confirmed on four-nodes privnet with BoltDB and `SessionExpirationTime` set to be 180 seconds. After new iterator session is added to the server, the subsequent persist took ~5m21s, see the log record `2022-06-17T18:58:21.563+0300`: ``` anna@kiwi:~/Documents/GitProjects/nspcc-dev/neo-go$
