Our wrapping optimization relied on the caller context having a TRY block,
but each context (including internal calls!) has an exception handling stack
of its own, which means that for an invocation stack of
entry
A.someMethodFromEntry() # this one has a TRY
A.internalMethodViaCALL() # this one doesn't
B.someMethod()
we get `HasTryBlock() == false` for `A.internalMethodViaCALL()` context, which
leads to missing wrapper and missing rollbacks if B is to THROW. What this
patch does instead is it checks for any context within contract boundaries.
Fixes#3045.

That's the way how C# node handles equality checks for stackitem.Interop types
for these points. Ref. https://github.com/nspcc-dev/neo-go/issues/3002#issuecomment-1591220501.
Along the way, add GT case for CryptoLib's bls12381Equal method. It should be there since #2940.

In this case emitted event parameters should match from invocation to
invocation. It's an error otherwise (and if the type is not Any).

Unfortunately, without pre-set user extended types configuration for events
and without --guess-eventtypes flag set we are allowed to rely only on manifest
information about types. Manifest can't give us a lot of information, but we
still need to be able to generate RPC binding. Arrays and structs are correctly
handled by the current code, but maps always rely on the fact that map's value
type is set. It's not true in the described case, so make the maps type convertor
handle this situation in a similar way how arrays are handled.
Without this commit the following panic occurs on attempt to generate RPC binding:

There are two ways of doing this: first one is to emit all notifications
parameter data into rpcbindings configuration on compile time (event if
the parameter has a simple type), and the second one is to fetch parameter
type from the manifest on rpcbinding file generation if needed (we always
have manifest at this stage, thus it's not a problem to retrieve necessary
information). The latter case is chosen to reduce the bindings configuration
file size.

Notification and its parameters may have any UTF8-compatible name
which is inappropriate for bindings configuration and for the resulting
RPC bindings file. This commit stores the prettified version of
notification's name and parameters that are ready to be used in the
resulting RPC binding without any changes.

The user should specify it via parameter's `extendedtype` field and
via upper-level `namedtypes` field of the contract configuration YAML.
Also, as we have proper event structure source, make the `--guess-eventtype`
compilation option and make event types guess optional.

Regular Client doesn't care much about connections, because HTTP client's Do
method can reuse old ones or create additional ones on the fly. So one request
can fail and the next one easily succeed. WSClient is different, it works via
a single connection and if it breaks, it breaks forever for this
client. Callers will get some error on every request afterwards and it'd be
nice for this error to be the same so that API users could detect
disconnection this way too.

If the contract was deployed then cache must be initialized after
in-memory data reset. If the contract isn't active yet, then no
cache will be initialized on deploy (i.e. on call to Initialize()
method by native Management).

Make the contracts cache initialization unified. The order of cache
iniitialization is not important and Nottary contract is added to the
bc.contracts.Contracts wrt P2PSigExtensions setting, thus no functional
changes, just refactoring for future applications.

It should be noted that the subscriber's channel is being removed from the
list of receivers and closed, but it is still *in the list of subscribers*
and no unsubscription is performed by WSClient. Which means that RPC server
keeps sending notifications to WSClient and WSClient keeps dropping them
(because there's no receiver for this subscription and it's OK, WSClient
can handle this and this behaviour is documented). However, it's still the
caller's duty to call Unsubscribe() method for this subscription.
