chore(metrics): use libevm metrics package and delete local metrics

- delete content of `metrics` package except `prometheus` package
- only keep subnet-evm specifics in `metrics/prometheus`
- Bring over refactoring and fixes done in ava-labs/libevm#103
- Bring over test refactoring done in ava-labs/libevm#103
