This code was never invoked since we had no native contract enabled
starting from some hardfork, Notary is the first one. And luckily, we
have plenty of tests that fail due to this bug.

It doesn't work for contracts enabled starting from non-nil hardfork:

It happens because ActiveIn hardfork wasn't taken into account during
`latestHF` computation. This commit also removes the reusage of
`activeIn` variable in deploy procedure, it's misleading and not
necessary startign from #3444.

This commit introduces a small new change
that implements the Hooks API and more
specifically the OnExecHook. This feature
can be used to implement test coverage
collection, tracing, breakpoints, and etc.
To be more specific, this commit:
1. adds a new `hooks` field to the `VM`
(this field contains the OnExecHook
function)
2. sets the default value of this hook
to be a NOP function
3. adds the `VM.SetOnExecHook` method

Signers are very important for notary checks and keeping/passing an additional

Most of the time people are interested in successful executions. Unfortunately,
unwrap package can't help here because of a different result structure (some
interface abstract can help, but it's still mostly stack-oriented and sessions
can be a problem), so this additional interface is needed.

Add a note about System.Runtime.GetNotifications refcounting to Domovoi
hardfork. Ref. https://github.com/neo-project/neo/pull/3301 and
https://github.com/nspcc-dev/neo-go/pull/3485.
Although NeoGo doesn't have anything to be updated, there's a
behaviour difference between C# and Go nodes before Domovoi hardfork, it
deserves a comment.

It's not correct to use an updated contract state got from Management to
check for the allowed method call. We need to use manifest from the
currently executing context for that. It may be critical for cases when
executing contract is being updated firstly, and after that calls
another contract. So we need an old (executing) contract manifest for
this check.
This change likely does not affect the mainnet's state since it's hard
to meet the trigger criteria, but I'd put it under the hardfork anyway.

This test ensures that NeoGo node doesn't have the DeepCopy problem
described in https://github.com/neo-project/neo/issues/3300 and fixed in
https://github.com/neo-project/neo/pull/3301. This problem leads to the
fact that Notifications items are not being properly refcounted by C#
node which leads to possibility to build an enormously large object on
stack. Go node doesn't have this problem.
The reason (at least, as I understand it) is in the fact that C# node
performs objects refcounting inside the DeepCopy even if the object
itself is not yet on stack. I.e. System.Runtime.Notify handler
immediately adds references to the notification argumetns inside
DeepCopy:
b1d27f0189/src/Neo.VM/Types/Array.cs (L108)b1d27f0189/src/Neo.VM/Types/Array.cs (L75)
Whereas Go node just performs the honest DeepCopy without references counting:
b66cea5ccc/pkg/vm/stackitem/item.go (L1223)
Going further, C# node clears refs for notification arguments (for array
and underlying array items). System.Runtime.GetNotifications pushes the
notificaiton args array back on stack and increments counter only for
the external array, not for its arguments. Which results in negative
refcounter once notificaiton is removed from the stack. The fix itself
(f471c0542d/src/Neo/SmartContract/NotifyEventArgs.cs (L84))
doesn't need to be ported to NeoGo because Go node adds object to the
refcounter only at the moment when it's being pushed to stack by
System.Runtime.GetNotifications handler. This object is treated as new
object since it was deepcopied earlier by System.Runtime.Notify handler:
b66cea5ccc/pkg/vm/stack.go (L178).
Thus, no functoinal changes from the NeoGo side. And we won't
intentionally break our node to follow C# pre-Domovoi invalid behaviour.

Do not use the updated contract state from native Management to perform
