[red-knot] Integrate formatter

[MichaReiser]

Summary

This is a first hacky approach to integrate the formatter into red-knot.

There are plenty of TODOs. The main questions is where and when we should write the formatted content and how we avoid that formatting requires two-passes for the cache to be "hot".

Test Plan

I ran red knot and it formated my files (all lints gone, whoops)

I still plan to land this PR eventually but aren't prioritising it right now. Deciding on a query system and exploring persistent caching is of higher importance right now and the prototype itself was enough for me to learn a lot about the challenge when it comes to integrate the formatter.
