[worker] Add worker from turtle-v2

[sjchmiela]

Why

We want to streamline DX of the worker part of EAS. Part of it is colocating all code in one repository.

How

Copied code over to eas-cli. Adjusted code — each commit represents a single piece of work towards adjusting code to this repository. The main changes are around removing dependency on turtle-v2 internal libraries.

One thing to figure out still is deployment process. I've added build-and-deploy-worker which is capable of deploying to staging and production. The question is how to automate it. In turtle-v2 we have system tests. Should we just copy them over to here? (Don't like that.) Should we streamline system tests and instead of having this weird turtle-v2-example repo, create project on the go? Should we deploy worker manually for now?

Test Plan

Deployed worker to staging. Ran system tests. They succeeded!! https://github.com/expo/turtle-v2/actions/runs/20042956545/job/57535011098
