Nit: it's called gas in invoke wrappers, should it be also gas here?

I'm switching from gas_left to gas because seems good enough.

I will leave gas_left in instructions this time because it comes from state.gas_left. This slightly limits the number of change.s

- Pass to and return gas counter to instructions implementations by
value, don't use ExecutionState::gas_left. This improves performance.
- Introduce Result type {status, gas}.
- Change StopToken to TermResult (strong alias of Result).
