eslint: Add eslint-plugin-package-json (#44559)

This eslint plugin will sort package.json files and apply other
cleanups, replacing the manual use of `sort-package-json` which we're
currently only applying to the monorepo root file.

The configuration is slightly complex, in that we want different
treatment for files in different places:
* Only js-packages require a `name` field.
* Only public js-packages require a description or version.
