Return computation used for scripts/transactinon on emulator

Issue To Be Solved

When testing/desining scripts and transactions it is sometimes very hard to know how computation will scale as state grows. If there was a way to get this data from the emulator it would make life a lot easier.

It is currently possible to get the meters for transactions but they are emitted as log entries and you have to parse the logs to get it out.

Yesterday on Discord we had a discussion about fixes metering, I think we lack some stuff from Cadence side to make this useful. I have few ideas, today planning to discuss with Cadence team.
