💥 Add Multi-Role-Based TimelockController Reference Implementation

[cairoeth]

🕓 Changelog

Adds a new contract TimelockController (closes #178), with unit, fuzz, and invariant tests. Contains code sourced from AccessControl — ideally, it would import it instead of duplicating functions (they are unedited).

NOTE: Some unrelated Solidity tests/files were "modified" because I ran the Forge formatter. We can modify the formatter settings to follow a specific sol style if there's one. (Note by @pcaversaccio: simply run pnpm prettier:fix to format all files).

(Note by @pcaversaccio) This PR also contains small documentation improvements regarding code comments and also fixes a small issue about a missing @view decorator in the _check_role function of the AccessControl contract. Eventually, it also fixes a small issue with the glob syntax in the package.json scripts to ensure OS-independent interpretation (see prettier-solidity/prettier-plugin-solidity#978).

I quickly fixed the prettier issue: you can simply run pnpm prettier:fix to have to format the files. I don't use forge fmt for multiple reasons. I also quickly fixed some typos. Will dive into the code either today or tomorrow hopefully.
