233307aca5 stackitem: completely drop MaxArraySize
Turns out C# VM doesn't have it since preview2, so our limiting of
MaxArraySize in incompatible with it. Removing this limit shouldn't be a
problem with the reference counter we have, both APPEND and SETITEM add things
to reference counter and we can't exceed MaxStackSize. PACK on the other hand
can't get more than MaxStackSize-1 of input elements.

Unify NEWSTRUCT with NEWARRAY* and use better integer checks at the same time.

Multisig limit is still 1024.

aab18c3083 stackitem: introduce Convertible interface
We have a lot of native contract types that are converted to stack items
before serialization, then deserialized as stack items and converted back to
regular structures. stackitem.Convertible allows to remove a lot of repetitive
io.Serializable code.

This also introduces to/from converter in testserdes which unfortunately
required to change util tests to avoid circular references.

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.

f57187e611 vm: throw unhandled exception with message instead of panic
The result is the same HALT state, but the exception message is the real
one got from user. Changes ported from C#:

1. Throw exception: 59b8ac73d2/src/neo-vm/ExecutionEngine.cs (L1448)
2. Prettify message: https://github.com/neo-project/neo-vm/blob/master/src/neo-vm/VMUnhandledException.cs#L28

The result is that instead of
```
2021-03-31T17:02:54.508+0300	WARN	contract invocation failed	{"tx": "2aefeb705f3a609df8767d9b45e036b9dd1eb77407e5732375981915668889b8", "block": 30640, "error": "error encountered at instruction 970 (THROW): runtime error: invalid memory address or nil pointer dereference"}
```

we'll get

6a4e312eac core: move GetPrice from core to interop
We have additional logic for getting BaseExecFee policy value. This
logic should be moved to interop context instead of being in Policer,
because Policer is just an interface over Policy contract.

After moving this logic to interop context, we need to use it to define
BaseExecFee instead of (Policer).BaseExecFee. Thus, moving
(*Blockchain).GetPrice to (*Context).GetPrice is necessary.
