Research exposing CKEditor 5 API as a global object

[jodator]

Provide a description of the task

Exposing CKEditor5 global object (available on window) and dot access to classes (base editor API). 

• it might require better naming for some classes/methods
• it might require to make CKE5 as main entry package, see also: Make ckeditor5 a peer dependency of all other packages #1061.

Requirements to met:

• Adding a plugin to a build (might be a new build type).
• Using imports from base editor plugins (core, engine, utils <EmitterMixin>, ui).
• Using imports from "common" plugins (widget, clipboard, ... ).
• Potential to solve CSS double import issue #8400.

TIL: you can load anything from the exported DLL:

So you could tinker with the exposed DLL. Not the best API though.

This could be improved somehow, though.

1. Real global object exposed on window.
2. Use own module ID plugin for webpack (docs, source).

Side note as for 1: I've tried to use libraryEntryPoint but it fails with DLL.

I would see: CKEditor('module:engine/model/position~Position'). But, it may be just a wish.

So this task can be also closed as the research proved that we're going with DLL + custom webpack plugin to expose global: #8521.
