Try to subscribe for headers firstly, and then if RPC server doesn't
have this ability, fallback to block subscriptions to manage transaction
awaiting.

Adjust names of all used structures, no need to duplicate `Waiter` everywhere,
we already in the `waiter` package. Also, adjust comments to Actor so that links
to Waiter are properly described in docs.

It can be used to work with the results of
CreateCallAndPrefetchIteratorScript() execution. The first item must be
an array and the optional second item must be an iterator, containing
remaining elements.

There is CreateCallAndUnwrapIteratorScript() which can traverse
iterator for nodes with sessions disabled. For other nodes this may
still be beneficial: if there is a small number of items, we might read
(or prefetch) all of them in one request. However, this script continues
to work even for large collections, returning both accumulated array and
remaining iterator.

There are use-cases when not only Actor, but also Invoker and even
simple RPC client must wait (e.g. sendtx or dumptx CLI commands). Actor
requires optional signers in constructor, and it's not always
appropriate to create Actor only to be able to use Waiter, sometimes
it's needed to use only Waiter without Actor.

New event is to notify the user about header's content by the moment
when block is stored (which happens after block's processing). This is
needed for proper Waiter work.

dBFT doesn't use validators got from this call to GetValidators callback,
because NeoGo doesn't properly set WithGetConsensusAddress, and thus
this call can be safely skipped. Instead, NeoGo fills NextConsensus field
by itself in NewBlockFromContext callback.
This commit technically doesn't perform any functional changes and doesn't
affect the problem described in #3253 in any way. This commit is just a
removal of the code that was never used by NeoGo library.
This commit is a direct consequence of https://github.com/nspcc-dev/dbft/issues/84.

We have cache update mechanism (Neo's cache votesChanged flag), it must
be used for current epoch and new epoch cached values update. And the
cached current/new epoch values themselves must always contain valid
information for the current/new epoch. These cached values must only be
changed once per epoch, never set them to nil.
This commit prevents CN node panic described in #3253 when dBFT tries
to retrieve new epoch validators with some votes modifications made
before at the same dBFT epoch.

StateRootInHeader depends on it, so we better immediately return error

I had some reason to suspect something is wrong here (but it's all OK). Even
though this is kinda tested in TestDeployGetUpdateDestroyContract, it uses
internal APIs and with neotest we can ensure it work OK for a complete tx/block
environment. So, won't hurt having these tests as well.
