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"}

core: move GetPrice from core

...
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.

core: introduce CheckReturnState constants
...
At the moment we should have 3 possible options to check return state
during vm context unloading:
* no check
* ensure the stack is empty
* ensure the stack is not empty
It is necessary to distinguish them because new _deploy method shouldn't
left anything on stack. Example: if we use _deploy method before some
ordinary contract method which returns one value. Without these changes
the contract invocation will fail due to 2 elements on stack left after
invocation (the first `null` element is from _deploy, the second element
is return-value from the ordinary contract method).

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.
