Port dev engines script from React

[zpao]

This brings in the script that we're using in React to make sure the dev environment is what we expect. It's slightly modified to require a file argument since we can't hardcode the path to the package.json that we want to use. Specifically it checks devEngines in package.json, which is something I made up (but correlates nicely with the engines field that npm sort of uses)

I confirmed this is working in React with

"scripts": {
  "preinstall": "node node_modules/fbjs-scripts/node/check-dev-engines.js package.json"
}
