This is the first step of {T259059}. Once complete, the extension will become totally broken, but put us on the right path to a working state. **Acceptance criteria** * Using the [[ https://www.npmjs.com/package/codemirror | basic CodeMirror package ]], identify which modules under the `@codemirror` namespace we need. * Package the files if necessary * Configure them in extension.json, registering them as [[ https://www.mediawiki.org/wiki/ResourceLoader/Package_files | package files ]] (which is the first bullet point of T272035) * Create new `ext.CodeMirror.v6.WikiEditor` module that is loaded when `$wgCodeMirrorV6` is set.

This is the first step of {T259059}. This will only put us in a basic working state with CodeMirror 6, with everything behind a temporary feature flag.

Relevant features of #wikieditor should still work, and you should still be able to save the page, etc.
