core: rename state.NEP17Balances to state.NEP17TransferInfo

Browse source 
Balances are to be removed from state.NEP17TransferInfo, so the remnant
fields are NextTransferBatch, NewBatch and a map of LastUpdatedBlocks.
These fields are more staff-related.

Also rename dao.[Get, Put, put]NEP17Balances and STNEP17Balances
preffix.

Also rename NEP17TransferInfo.Trackers to LastUpdatedBlockTrackers
because NEP17TransferInfo.Balances are to be removed.
