vm: don't use Stack for istack
...
We don't use all of the Stack functionality for it, so drop useless methods
and avoid some interface conversions. It increases single-node TPS by about
0.9%, so nothing really important there, but not a bad change either. Maybe it
can be reworked again with generics though.

vm: simplify slot and make it private
...
Hiding refcounter inside a slot is actually a good idea, but it makes the
structure somewhat bigger, especially given that the refcounter is the same
and belongs more to VM or Context. New structure is a bit more efficient:
name old time/op new time/op delta

ScriptPushPop/4-8 1.52µs ± 1% 1.47µs ± 1% -3.14% (p=0.008 n=5+5)
ScriptPushPop/16-8 3.66µs ± 1% 3.54µs ± 1% -3.24% (p=0.008 n=5+5)
ScriptPushPop/128-8 24.7µs ± 1% 23.2µs ± 1% -6.14% (p=0.008 n=5+5)
ScriptPushPop/1024-8 183µs ± 1% 173µs ± 1% -5.01% (p=0.008 n=5+5)

ScriptNestedRefCount-8 241kB ± 0% 241kB ± 0% ~ (p=0.333 n=5+4)

ScriptPushPop/128-8 8.70kB ± 0% 8.70kB ± 0% ~ (all equal)
ScriptPushPop/1024-8 73.2kB ± 0% 73.2kB ± 0% ~ (all equal)
name old allocs/op new allocs/op delta
ScriptFibonacci-8 3.17k ± 0% 3.17k ± 0% -0.03% (p=0.008 n=5+5)
ScriptNestedRefCount-8 10.7k ± 0% 10.7k ± 0% ~ (all equal)
ScriptPushPop/4-8 8.00 ± 0% 8.00 ± 0% ~ (all equal)

ScriptPushPop/1024-8 2.05k ± 0% 2.05k ± 0% ~ (all equal)
It'd be especially nice to internalize static slot, but as we can't compare
slices it's not possible.

vm/core: add ID support for SYSCALL, redo interop registration
...
This solves two problems:
* adds support for shortened SYSCALL form that uses IDs (similar to #434 , but
for NEO 2.0, supporting both forms), which is important for compatibility
with C# node and mainnet chain that uses it from some height
* reworks interop plugging to use callbacks rather than appending to the map,
these map mangling functions are clearly visible in the VM profiling
statistics and we want spawning a VM to be fast, so it makes sense
optimizing it. This change moves most of the work to the init() phase
making VM setup cheaper.
Caveats:
* InteropNameToID accepts `[]byte` because that's the thing we have in
SYSCALL processing and that's the most often usecase for it, it leads to
some conversions in other places but that's acceptable because those are
either tests or init()
* three getInterop functions are: `getDefaultVMInterop`, `getSystemInterop`
and `getNeoInterop`
Our 100K (1.4M->1.5M) block import time improves by ~4% with this change.

This allows easier reuse of opcodes and in some cases allows to eliminate
dependencies on the whole vm package, like in compiler that only needs opcodes
and doesn't care about VM for any other purpose.
And yes, they're opcodes because an instruction is a whole thing with
operands, that's what context.Next() returns.
