Out of the box today, CRA produces numbered vendor chunks. They look like this in production:

File sizes after gzip:

  146.17 KB       build/static/js/7.f5a20c19.chunk.js
  39.39 KB        build/static/js/8.5cf7927d.chunk.js

And like this in development:

This is a good default for production, following webpack's guidance (splitChunks.name: false) to create stable, cacheable names.

In development, though, when I'm trying to understand exactly what code is delivered when, I'd like to know more about what goes in to those chunks.

This PR sets splitChunks.name to true in development, producing vendor chunk names like this:

Is this something others would be interested in?

@iansu @mrmckeb @ianschmitz @petetnt I know you probably have a ton of stuff to review right now, but this is a 1-line change that shouldn't take a lot of thought. Can you take a look?

I'm not opposed to this, any thoughts @ianschmitz or @iansu?
