stackitem: don't copy existing slices for TryBytes
...
Most often we only need to read them and it doesn't require copying. Make an
explicit copy (and copy only things we need!) where needed.
After the recent neo-vm tests update our vm package testing time jumped to
~12s, with this change it's now more like ~8s.

stackitem: add NewPointerWithHash() to save on hash calculations
...
Inspired by neo-project/neo-vm#352 . We can't directly compare slices, so we're
better optimize things we already have. At the same time this code would
behave a bit different if A is to call B and then B is call A and then some
pointer from the first A invocation is to be compared with a pointer from the
second A invocation. Not sure it really matters.

stackitem: implement marshaling to JSON with types
...
There are 2 kinds of JSON marshaling:
1. Lossy raw marshaling, when type information is lost and
map keys are expected to be valid utf-8 strings.
2. Almost lossless marshaling, which can handle any non-recursive item.
Interop value preserves only type.
This commit implements the second.

We're able to serialise Buffer stackitem, but can not deserealise it
