build(compat): use a treeless TypeScript clone (#6193)

**What's the problem this PR addresses?**

Building the latest TypeScript patch requires fetching
https://github.com/arcanis/typescript,
https://github.com/microsoft/typescript, and
https://github.com/merceyz/typescript which, according to git, requires
fetching 1.87 GiB, 452 MiB, and 42 MiB of data and produces a 2.7GB
`.git` folder.

**How did you fix it?**

Fork TypeScript to https://github.com/yarnpkg/TypeScript and push the
branches required to build all the patches to it and change the script
to use a treeless clone of it which only needs to fetch 55 MiB of data
and produces a 74MB `.git` folder.

Depends on 
- #6186

**Checklist**
- [x] I have read the [Contributing
Guide](https://yarnpkg.com/advanced/contributing).
- [x] I have set the packages that need to be released for my changes to
be effective.
- [x] I will check that all automated PR checks pass before the PR gets
reviewed.
