This pull request introduces @next/react-refresh-utils. It's an experimental package containing all the code necessary for React Refresh (aka Fast Refresh or hot reloading).

It's created largely by following implementation advice by @gaearon given in facebook/react#16604 (comment).

It also includes MIT-Licensed code copied directly from the Metro JavaScript Bundler, with an appropriate license header in the file.

This pull request does not do anything alone.

Wiring this into Next.js and adding tests for the expected behavior will be handled as a separate pull request.

@Timer Timer added this to the 9.3.6 milestone Apr 18, 2020
