Enable caching interpreter shared state

[janezpodhostnik]

Problem Definition

A while ago Cadence added the ability to cache interpreter shared state https://github.com/onflow/cadence/issues/2048 for optimisation purposes.

The original estimate for speedup was 15%. Because of changes done since then:

• other parts of the transaction have been optimised
• there is one more pre-transaction step that would benefit from the optimisation

The estimate should be greater now.

Proposed Solution

Implement the interpreter state reuse functions

func (env *facadeEnvironment) SetInterpreterSharedState(state *interpreter.SharedState) {
    // NO-OP
}

func (env *facadeEnvironment) GetInterpreterSharedState() *interpreter.SharedState {
    return nil
}

But there is a twist! When I did that in the past tests started failing and I never figured out why: https://github.com/onflow/flow-go/pull/3942

Definition of Done

• Implement interpreter shared state reuse within a transaction
