dao: drop DAO interface
...
It's a remnant from the days when we had Simple and Cached DAO
implementations, now it makes zero sense.

storage: simplify (*MemCachedStore).Put/Delete interface
...
They never return errors, so their interface should reflect that. This allows
to remove quite a lot of useless and never tested code.
Notice that Get still does return an error. It can be made not to do that, but
usually we need to differentiate between successful/unsuccessful accesses
anyway, so this doesn't help much.

native: optimize totalSupply operations during token burn/mint
...
We burn GAS in OnPersist for every transaction so some buffer reuse here is
quite natural.
This also doesn't change a lot in the overall TPS picture, maybe adding some
1%.

native: move required balance check to token contracts
...
Which duplicates the check, but deduplicates error path. This check forced
double balance deserialization which is quite costly operation, so we better
do it once.
It's hardly noticeable as of TPS metrics though, maybe some 1-2%%.

core: get native nep17 balance from contract storage
...
Not from DAO's items with storage.STNEP17Balances prefix, because
changes are reflected there only after notifications processing. And
this happens only after the transaction script is executed, but there
might be cases when we need to get the balance that was updated
earlier during the same transaction processing.
Affects storage dumps.
