Co-authored-by: Erik Zhang <erik@neo.org>

Added a new `MemoryReader` class for deserialization. It significantly improves neo's performance by avoiding memory copies during deserializations.

Notifications are deep copied as immutable.

* Native: store ID->hash map in ContractManagement, add iterator

That probably is the lighest design possible, store and retrieve hashes
only. But it can be expanded to return full contract state (getContractByID,
for example) and probably even iterate over contract states.

* Payloads: implement Conflicts attribute

Closes #1991.

* Update src/Neo/Ledger/MemoryPool.cs

* Fix conflicting tx fees accounting

Fix the comment #2818 (comment).

* Reformat code and improve variables naming

Fix Vitor's comments.

* Make comments more clear and adjust variables naming

Fix Owen's feedback.

* Fix Conflicts attribute verification

Consider the case when transaction B has the hash of transaction A
in the Conflicts attribute and transaction B is on-chain. Let the
transaction C has the hash of transaction A in the Conflicts attribute.
Then transaction C still should be able to pass verification and should
be accepted to the subsequent block, because transaction A isn't on chain
and transaction A will never be accepted.

Thanks to Owen for testing, this case is described at the
#2818 (review).
The expected behaviour in the described case is that TXID-D and TXID-E will
be successfully accepted to the mempool and to chain, because the conflicting
TXID-A is not on chain (and it's OK that the hash of TXID-A is on-chain as
the conflicting hash).

* Fix formatting, comments and add a testcase for conflicting mempool txs

* Add one more testcase for conflicting transactions

Testcase provided by Vitor in #2818 (comment).

* Implement economic adjustments for Conflicts attribute

Transaction that conflicts with mempooled transactions have to pay
larger network fee than the sum of all conflicting transactions in
the pool that have the same sender as the newcomer.

Port the nspcc-dev/neo-go#3031.

* Remove Trimmed value

* Check signers of on-chained conflict during new tx verification

Fix the problem described in
#2818 (review).

During new transaction verification if there's an on-chain conflicting
transaction, we should check the signers of this conflicting transaction.
If the signers contain payer 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 in this case.

* Properly handle duplicating Conflicts hashes from the persisted transactions

* Store signers of all conflicting on-chain transactions with the same Conflicts attribute

Store not only signers of the latest conflicting on-chain transaction, but
signers of all conflicting transactions with the same attribute.

* MemoryPool: consider signers intersection on Conflicts check

This patch should be a part of fd1748d, but
was accidentally skipped. This patch matches exactly the NeoGo behaviour that
was added in nspcc-dev/neo-go#3061 and that was
discussed earlier in #2818 (comment).

Fix the issue described in #2818 (comment).
