Subject: [PATCH] feat(triedb): expose backend for custom use (#183)

## Why this should be merged

To override the standard trie behavior for custom databases in
`core/state/database.go`, custom methods may need to be defined on the
backend database.

## How this works

Exposes `backend` interface for the API

## How this was tested

No tests necessary - isn't used in `libevm`.
