[Epic] Anticheat runtimes (EAC and BattlEye)

[CommandMC]

It is now possible to manage and enable anticheat runtimes in the launcher
Current issues:

• BattlEye runtime doesn't work, the Wine-GE patch for it seems to not apply. Not sure why, needs more testing
  Nevermind, the runtime works, the only game I was testing with (The Cycle: Frontier) did not work correctly

---

Use the following Checklist if you have changed something on the Backend or Frontend:

• Tested the feature and it's working on a current and clean install.
• Tested the main App features and they are still working on a current and clean install. (Login, Install, Play, Uninstall, Move games, etc.)
• Created / Updated Tests (If necessary)
• Created / Updated documentation (If necessary)

Beside the error evaluation, this is a clean code.
But the error handling is important, so need to reject the pr.
How you handle the errors is your choice. You can do it in the backend or in the frontend.

Btw you could also write backend tests. Downloading/unzipping etc. You can have a look at heroic-wine-downloader tests, how i simulate a url request, download etc.

Wasn't done with this yet, otherwise I would've marked it as ready for review

I understand your concerns and will implement error handling in the new functions. As for tests, other than examples, do you have a piece of documentation or something I can look at, to make sure I'm doing it right?

Ah sorry didn't saw the wip. Ok i will resolve all comments for now.
Jest documentation: https://jestjs.io/docs/getting-started
Everything is setup already. You just need to create a new *.test.ts and write test's there.
If you need help i can try to write the first test for you as an example.

Alright, error handling is now in place. Let me know what you think, I'll take a look at tests now then

[CommandMC]

There are still a lot of tests missing, although the functionality itself might be nice to have for a beta release
