This implementation is a bit smaller and still has the following benefits:

* No need of app/javascript/packs/custom.js
For custom stylesheet, it typically has only
"require('../styles/custom.scss')" and is redundant.

* No need to extract vendor stylesheet to another asset
Extracting vendor stylesheet could be forgotten by developers who do not
use custom stylesheet.

* Fix #2922 - Load stylesheet from "custom.css" entrypoint when present

This is pretty much the same way it worked as before, albeit with
having to create app/javascript/packs/custom.js with
require('../styles/custom.scss') (or whatever you want really), which
will be a blank slate for you to import whatever you want

* Remove old assets directory

* Extract font-awesome into common.css and always load it

* Only load Intl data for current language

* Extract common chunk only from application.js and public.js

* Generate locale packs, avoid caching on window object

* Create common chunk rather than vendor chunk

vendor chunk is a set of modules provided by external vendors, but now we
can have a chunk as a set of modules shared by multiple entry points,
which could be more efficent than having vendor chunk.

* Start rails-ujs in common.js

This is used by /settings/two_factor_authentication.

Fixes AuthorizationController tests

Fix flashes partial render error for controllers which don't inherit from application controller (#2400)

* Add failing spec for oauth/authorized_applications controller

* Use explicit reference to flashes partial from admin layout

Because some of the controllers which use the admin layout do not inherit from
application controller, this partial is not in their view path.
