core, rpc: use Seek to iterate over NEP* transfers
The results are controversial a bit. MemoryPS is a special storage and the new approach doesn't help it to iterate through NEP17 transfers. However, on long distances (if transfers are requested for more than 1000 blocks, which is ~4.1 hours of mainnet chain) both LevelDB and BoltDB perform good enough with the new approach. Taking into account the fact that default value for the query period of `getnep17transfers` RPC handler is a week (~40K mainnet blocks) we can sacrifice MemoryPS performance in favour of BoltDB and LevelDB optimisation. Close #2263.
