Add Yarn constraint to validate references in tsconfig.json and tsconfig.build.json against internal dependencies

[mcmire]

It is critical that if your package relies on another package within the repo, that you add that package not only as a dependency, but you also add that package to the references field in both tsconfig.json and tsconfig.build.json. Doing so ensures that your package is being compiled with the correct types at build time.

Furthermore, it is critical that the list of references in tsconfig.json and tsconfig.build.json are the same, except that each reference in tsconfig.build.json ends in /tsconfig.build.json. Doing so ensures that the exact same set of types are used in development as production.

It is easy to miss one or both of these items, especially when creating a new package.

Now that we are using JavaScript constraints, we can check both using constraints.
