feat(advanced): foundry-fork-db

[yash-atreya]

Motivation

The fork-db functionality was extracted from foundry as foundry-fork-db. This is a generic tool to create and manage forks.

foundry's current forking mechanism and management of multiple forks is based on this.

Solution

Demonstrate a minimal example of how this works using SharedBackend and BlockchainDb.

PR Checklist

• Added Documentation
• Breaking changes

[mattsse]

cool, this should also demonstrate how to use it with revm, like using the Database API and transacting a transfer for example

[klkvr]

nice, lgtm!

I think we should also eventually demonstrate how foundry-fork-db can be plugged into Provider's call and estimate_gas fns to leverage local EVM simulation and caching of individual storage slots
