Do not wait until wsReader routine gracefully finishes its work before
WS connection close. Instead, firstly close the connection, and after
that wait for proper wsReader exit.
It's a harsh way, but I don't have any other options to try, because
wsReader routine hangs on `ws.ReadMessage()` operation for more than
ReadDeadline (more than 5 seconds) during test cleanup which results in
the test timeout.

Made connections in parallel to check the limit and attempt to make one
more connection beyond the limit. Only "default" test case is failing,
because default number of connections is 64 (quite large for slow
runners). The failure reason is:
* given ~1 second for [dealing + request] per connection (time is taken
from the test log)
* by the moment 65-th connection is reached, some connections from the
start of the test have died due to inactivity (this process literally
takes 1 minute)

1. Replace isFinished atomic variable with a channel, no functional changes
here, just use more common way as all our services do.
2. Do not check erors from SetReadDeadline and ReadMessage on exit. It
seems to be not quite right because connection is not closed by this
moment, and thus, these error checks are racy.
3. Add read timeout for the message reader. It is needed because some
tests may leave message unread in the end which results in hanging
test cleanup.
4. Add drain loop to message reader in order not to block WS reader on
sending message.

It's clear that TestBadSubUnsub is hanging on test cleanup, in
particular, on attempt to wait for wsRead routine to exit. The only
place where wsRead routine may hang is sending to msgCh in case if
receiver is not going to read from this channel:

Default http.Client and http.Transport can be really slow. Also on
windows Timeout: time.Second was not enough. Probably network related
issue. As mentioned in https://github
.com/nspcc-dev/neo-go/issues/2975#issuecomment-1750523651 forcely use
only tcp4 and FallbackDelay: -1. This made TestRPC little bit faster so
gh windows runner can manage it without timeout or POST request fails.

Previously user should Start server in a separate goroutine. Now
separate goroutine is created inside the Start(). For normal server
operation, the caller should wait for Start to finish. Also, fixed

`getrawnotarytransaction` takes a transaction hash and attempts to find
the corresponding transaction in the notary requests mempool. It searches
through all the verified main and fallback transactions.
`getrawnotarypool` returns hashes of all the verified transactions,
including both main and fallback transactions.
Additionally add struct result.RawNotaryPool.

Do not block subscribers until the unsubscription request to RPC server
is completed. Otherwise, another notification may be received from the
RPC server which will block the unsubscription process.
At the same time, fix event-based waiter. We must not block the receiver
channel during unsubscription because there's a chance that subsequent
event will be sent by the server. We need to read this event in order not
to block the WSClient's readloop.
