4be692193e vm: allow parsing scientific JSON numbers 
52-bit precision is not enough for our 256-bit VM, but this value
matches the reference implementation, see the
https://github.com/neo-project/neo/issues/2879.

MaxIntegerPrec will be increased (or even removed) as soon as the
ref. issue is resolved.

71bcb8bade native: allow to use EQUAL opcode for BLS12-381 points comparison 
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.

433275265f *: use require.ErrorIs instead of require.True(t, error.Is()) 
This is just a much better way to do the same thing. Inspired by

a8d2df874f stackitem: limit JSON size in ToJSONWithTypes 
Also do not limit depth. It was introduced in e34fa2e915 as a simple
solution to OOM problem. In this commit we do exactly the refactoring
described there. Maximum size is the same as stack item size and
can be changed if needed withouth significat refactoring.
`1 MiB` seems sufficient, though.

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.
