Upstream the Prism RBS rewriter changes

[KaanOzkan]

It's a large branch so we should try to extract PRs out of it as often as possible. Code will not be triggered.

We should first open the extracted PR against Shopify/sorbet and get team feedback. Some of these files are still going through changes, we should prioritize the ones with less volatility.

Ensure that each file goes through a cleanup before opening a PR: #764

Next steps cc @amomchilov

• Wait for reviews/merge on open PRs
• Check the diff between ko/rbs-over-prism and master
  • Currently not rebased, it should be easier to create a duplicate branch, condense it into a single commit and then git rebase master
  • Open PRs for any of the left over diff
• Enable the RBS Rewriter with Prism
  • In pipeline.cc: https://github.com/sorbet/sorbet/blob/34b2f4c70da8e562bf0b9e7667d06b12f315f20c/main/pipeline/pipeline.cc#L276 & https://github.com/sorbet/sorbet/blob/34b2f4c70da8e562bf0b9e7667d06b12f315f20c/main/pipeline/pipeline.cc#L441
