ee4b8f883b core: check signers of on-chained conflict during new tx verification
During new transaction verification if there's an on-chain conflicting
transaction, we should check the signers of this conflicting transaction.
If the signers intersect with signers of the incoming transaction, then
the conflict is treated as valid and verification for new incoming
transaction should fail. Otherwise, the conflict is treated as the
malicious attack attempt and will not be taken into account;
verification for the new incoming transaction should continue.

This commint implements the scheme described at
https://github.com/neo-project/neo/pull/2818#issuecomment-1632972055,
thanks to @shargon for digging.

433275265f *: use require.ErrorIs instead of require.True(t, error.Is())
This is just a much better way to do the same thing. Inspired by
nspcc-dev/neofs-sdk-go#407.

7d6f087337 storage: drop (KeyPrefix).Bytes() API
It allocates and most of the time we can avoid that.

7dc8fc443f dao: simplify buffer management for private DAO
Private DAO is only used in a single thread which means we can safely reuse
key/data buffers most of the time and handle it all in DAO.

Doesn't affect any benchmarks.

9d2ef775cf 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.

4c39b6600d *: store application long along with tx/block
Two times less keys inserted into the DB per tx leads to ~13% TPS
improvement. We also drop one goroutine with it which isn't bad as well.

856385b106 dao: use custom storage prefix
We use 2 prefixes for storing items because of state synchronization.
This commit allows to parametrize dao with the default prefix.

5f9d38f640 core: refactor (*DAO).StoreAsTransaction
Squash (*DAO).StoreAsTransaction and
(*DAO).StoreConflictingTransactions. It's better to keep them this way,
because StoreAsTransaction is always followed by
StoreConflictingTransactions, so it's an atomic operation.

The logic wasn't changed.

b483c38593 block/transaction: add network magic into the hash
We make it explicit in the appropriate Block/Transaction structures, not via a
singleton as C# node does. I think this approach has a bit more potential and
allows better packages reuse for different purposes.

Two changes being done here, because they require a lot of updates to

It also removes GetType and GetScript interops, both are obsolete in Neo 3.

65503aa9b4 core: add nonce field to transaction
1. Closes #840: added Nonce field to transaction.Transaction and
removed Nonce field from transaction.MinerTx

2. Added following methods to different tx types:
  - NewMinerTx()
  - NewMinerTxWithNonce(...)
  - NewEnrollmentTx(...)
  - NewIssueTx()
  - NewPublishTx(...)
  - NewRegisterTx(...)
  - NewStateTx(...)
in order to avoid code duplication when new transaction is created.

3. Commented out test cases where binary transaction/block are used.
These test cases marked with `TODO NEO3.0: Update binary` and need to be
updated.

4. Updated other tests

5. Added constant Nonce to GoveringTockenTx, UtilityTokenTx and genesis
block to avoid data variability. Also marked with TODO.
