It's just not possible to use maps in invokers/actors without this. And maps
have too many combinations to try pushing them into a type switch, that's
where reflection kicks in and solves it easily.

Mostly it's about Go 1.22+ syntax with ranging over integers, but it also
prefers ranging over slices where possible (it makes code a little better to
read).
Notice that we have a number of dangerous loops where slices are mutated
during loop execution, many of these can't be converted since we need proper
length evalutation at every iteration.

Some clients need more flexible awaiting options (e.g. for short-blocks
networks). The default behaviour is not changed, all exported APIs are
compatible. Ref. https://github.com/nspcc-dev/neofs-node/issues/2864.

pollTime is never 0 since MillisecondsPerBlock protocol configuration value
is present in `getversion` RPC response since 0.97.3 release. We don't have such
old RPC servers in the network anymore, thus this fallback code may be
safely removed.

`makeWsRequest` creates a channel for response and waits for it. If between
creating the channel and starting the reading `select` connection is lost
(`writerDone` channel is closed), nothing reads from the channel and a
deadlock appears. Looking at "done" channels when transferring RPC data
solves the issue. Closes#3530.

Every client's (Un)Subscription call does two things: an RPC call and a
subscription map lock (two of maps currently). If we imagine that there is
one routine that tries to subscribe (A) and one routine that tries to
unsubscribe (B), the following sequence can happen:
0. Current number of subscriptions is X
1. B does an RPC and makes number of subscriptions X-1
2. A does an RPC and makes number of subscriptions X again
3. A holds subscription locks and rewrites client's subscription state
(subscription with ID X now points to a different channel; channel that
was registered by B is lost and is not related to any real subscription
but is still included in the `receivers` map)
4. B holds subscription locks and drops subscription X (first, it is an
error and we have just lost a subscription that we think was made
successfully second, we have lost a channel in the `receivers` map, and
no corresponding subscription points to it)
5. X subscription is received by the WS client (in practice it is a new
block, 100ms, quite often to be sure this issue happens every hour), we
range through the receivers, see no corresponding subscription, and
panic.
Closes#3093.

Signers are very important for notary checks and keeping/passing an additional
copy of them is very inconvenient. Exposing them from invoker makes them
available in actors too.

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.

Fix#3130. "Exception" is used for name since it's shorter and that's the name
used in JSON. "VMFault" was also considered as well as "FaultException"
(which mirrors result.Invoke).

FaultException can be non-empty even in Halt state when there were
problems with stack marshaling to JSON.

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.
