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.

9673a04009 core: allow to add several headers with StateRootInHeader on
Problem: with StateRootInHeader setting on only one header of height N+1
can be added to the chain of height N, because we need local stateroot
to verify headers (which is calculated for the last stored block N).
Thus, adding chunk of headers starting from the current chain's heigh
is impossible and (*Blockchain).AddHeaders doesn't have much sense.

Solution: verify header.PrevStateRoot only for header N+1. Rest of the
headers should be added without PrevStateRoot verification.

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.

ed3cef81cc core: allow to read states for non-contract verifications
C# does it this way now:
  callFlags = !witness.VerificationScript.IsStandardContract() ? CallFlags.ReadStates : CallFlags.None

So non-standard scripts _always_ have access to state and standards ones just
don't care (their code is known and it doesn't touch state).
