Problem: gas meter not reset per transaction during tracing

Affects: `debug_traceTx/Block`

Gas Meter should be reset per tx, [see this commit](https://github.com/VictorTrustyDev/fork-evmos/pull/3/commits/09228277293a902e7d37d8bff5a088c33afa8a9b) (don't see the entire PR, just the commit)

Start with the debug_traceTx and debug_traceBlock entry points named in the issue, then inspect the referenced commit for the intended gas-meter behavior. Done means the gas meter is reset separately for each transaction during tracing, rather than carrying state between transactions.
