d3672eb14a core: use BaseExecFee from InteropContext instead of Blockchain's one
The InteropContext's one contains all relevant fee changes applied in
the prevouse transactions of the current block.

544f2c2cb2 core: use proper storage price within the whole interop context
We shouldn't use StoragePrice from Blockchain because its dao doesn't
contain the whole set of changes from previouse transactions in the
current block. Instead, we should use an updated storage price for
each transaction and retrieve the price from cached DAO.

91a4bc5beb core: use proper DAO to get ExecFeeFactor
The usage of the Blockchain's one leads to the same ExecFeeFactor within
a single block. What we need is to update ExecFeeFactor after each
transaction invocation, thus, cached DAO should be used as it contains
all relevant changes.

9bfb3357f2 storage: add "private" mode to MemCachedStore
Most of the time we don't need locking on the higher-level stores and we drop
them after Persist, so that's what private MemCachedStore is for.

It doesn't improve things in any noticeable way, some ~1% can be observed in
neo-bench under various loads and even less than that in chain processing. But
it seems to be a bit better anyway (less allocations, less locks).

aefb26255a dao: drop DAO interface
It's a remnant from the days when we had Simple and Cached DAO
implementations, now it makes zero sense.

cda1c75db3 core: drop GetStandBy* methods
They're misleading now that we have variable number of committee
members/validators. The standby list can be seen in the configuration and the
appropriate numbers can be received from it also.

c942402957 blockchainer: drop Policer interface
We never use it as a proper interface, so it makes no sense keeping it this
way.

83d0b2f465 interop: move invocation counter from VM to Context

29cda5112a vm: simplify NEF loading by providing a special method
Offsets are still handled outside of VM to avoid introducing manifest

f96d9d168e native/interop: use oracle request signers for oracle response witness
Oracle responses must use the same set of signers as oracle requests even
though the transaction itself is signed by oracle nodes/contract.

We can probably improve interop.Context by removing Tx field completely and
adding more functionality to Container, but it's not very convenient for
VerifyWitness and will require adding more stub-like methods for Block, so Tx
is used for now (and we do have it in every relevant case).

9875799893 transaction: add new Rules witness scope
See neo-project/neo#2622. The implementation is somewhat asymmetric (and not
very efficient) for binary/JSON encoding/decoding, but it should be
sufficient.

2808f6857d interop: don't allocate for Functions and Notifications in New
Functions are usually immediately replaced (and it's OK for them to be nil,
searching through an array with length of zero is fine), Notifications are
usually appended to (and are absolutely useless in verification contexts).

13da1b62fb interop: fetch baseExecFee once and keep it in the Context
It never changes during single execution, so we can cache it and avoid going
