eb7bd7b99b core: optimize storageFind 
Because `Map` stores elements in arbitrary order, addition of new
element takes linear time (`Index` iterates over all keys). Thus our
`storageFind` is actually quadratic in time. Optimize this by creating
map from sorted slice.

cfe41abd35 vm: fix OOM during nested structure cloning 
Resulting item can't have more than MaxStackSize elements. Technically this
limits to MaxStackSize cloned elements but it's considered to be enough to
mitigate the issue (the next size check is going to happen during push to the
stack). See neo-project/neo#2534, thanks @vang1ong7ang.

b9ff07f32c stackitem: add limit to serialized items 
Standard binary serialization/deserialization is mostly used in VM to put/get
elements into/from storage, so they never should exceed MaxSize (otherwise one
won't be able to deserialize these items).

This patch leaves EncodeBinaryStackItem unprotected, but that's a streaming
interface, so it's up to the user of it to ensure its appropriate use (and our
uses are mostly for native contract's data, so they're fine).

e34fa2e915 stackitem: limit JSONization nesting level 
We can have very deep reference types and attempt to JSONize them can easily
lead to OOM (even though there are no recursive references inside). Therefore
we have to limit them. While regular ToJSON() is buffer size limited to
MaxSize, ToJSONWithTypes is not and limiting it to MaxSize output will require
substantial rewriting effort while not really providing fair result, MaxSize
is more about stack item size while its JSON representation can be much bigger
because of various overheads.

Initial thought was to limit it by element count based on
MaxIteratorResultItems, but the problem here is that we don't always have this
limit in contexts using ToJSONWithTypes (like notification event
marshaling). Thus we need some generic limit which would be fine for all
users.

We at the same time have maxJSONDepth used when deserializing from JSON, so
it can be used for marshaling as well, it's not often that we have deeper
structures in real results.

Inspired by neo-project/neo#2521.

6879cbcdcc stackitem: properly detect recursive references during serialization 
If we're done with element it no longer can lead to recursion error, so fix
cases like `[arr, arr]` where we have two copies of `arr` trigger this error
for no good reason (there is no recursion there).
