Provide developer utils for foundry

[mmv08]

Context / issue

When developing contracts for Safe with foundry, I ended up writing a lot of boilerplate code for signing, deploying safes and executing transactions. Similar to https://github.com/colinnielsen/safe-tools. For the best developer experience, we should provide this out of the box.

Proposed solution

Provide a developer tools package for foundry

Alternatives

• Do nothing
• Promote https://github.com/colinnielsen/safe-tools
