Create package to install foundryup

[cortisiko]

Description

We need to create a shared npm package for Foundry installation that can be used by both our extension and mobile clients. Currently, we maintain similar Foundry installation scripts in separate repositories, which creates unnecessary duplication and maintenance overhead.
This work stems from a recent discussion (https://consensys.slack.com/archives/CTQAGKY5V/p1746640108941359?thread_ts=1746626580.571289&cid=CTQAGKY5V) where we identified an opportunity to package the Foundry installation work from the extension PR (MetaMask/metamask-extension#28393) into a reusable package.

Acceptance Criteria

• Create an npm package that handles Foundry installation and configuration
• Ensure e2e tests that use Anvil (Foundry) pass in both clients
