fix(npm): improve peer dependency resolution (#17835)
This PR fixes peer dependency resolution to only resolve peers based on
the current graph traversal path. Previously, it would resolve a peers
by looking at a graph node's ancestors, which is not correct because
graph nodes are shared by different resolutions.

It also stores more information about peer dependency resolution in the
lockfile.

This directory contains the typescript compiler and a small compiler host for the runtime snapshot.

How to upgrade TypeScript.

The files in this directory are mostly from the TypeScript repository. We currently (unfortunately) have a rather manual process for upgrading TypeScript. It works like this currently:

  1. Checkout denoland/TypeScript repo in a separate directory.
  2. Add Microsoft/TypeScript as a remote and fetch its latest tags
  3. Checkout a new branch based on this tag.
  4. Cherry pick the custom commit we made in a previous release to the new one.
  5. This commit has a "deno.ts" file in it. Read the instructions in it.
  6. Copy typescript.js into Deno repo.
  7. Copy d.ts files into dts directory.
  8. Review the copied files, removing and reverting what's necessary

So that might look something like this:

git clone https://github.com/denoland/TypeScript.git
cd typescript
git remote add upstream https://github.com/Microsoft/TypeScript
git fetch upstream
git checkout v3.9.7
git checkout -b branch_v3.9.7
git cherry pick <previous-release-branch-commit-we-did>
npm install
