Inspired by https://github.com/neo-project/neo/pull/3558, although this
PR fixes different implementation of stackitem serializatior that is
used outside of VM.

Mostly it's about Go 1.22+ syntax with ranging over integers, but it also
prefers ranging over slices where possible (it makes code a little better to
read).
Notice that we have a number of dangerous loops where slices are mutated
during loop execution, many of these can't be converted since we need proper
length evalutation at every iteration.

And refactor some code a bit, don't use bytes.Clone where type-specific
helpers may be used instead.

Revert 5f6c01336c, remove all multierror
related nolint comments and use multierror wrapping instead.

Fix the following linter warning:
```
indent-error-flow: if block ends with a return statement, so drop this else and outdent its block (move short variable declaration to its own line if necessary) (revive)
```

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.

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.

Everywhere including examples, external interop APIs, bindings generators
code and in other valuable places. A couple of `interface{}` usages are
intentionally left in the CHANGELOG.md, documentation and tests.
Share parameters parsing code between 'contract invokefunction' and
'vm run' commands. It allows VM CLI to parse more complicated parameter
types including arrays and file-backed bytestrings.
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.

Doesn't change much, but still simpler.
