WikiEditor's ResizingDragBar makes the editor resizable, so we need to
set the height to 100%. This was attempted in Ib49d1d9e71 and
I4deeda192b but both ultimately suffer from race conditions. Instead
we're setting the height in WikiEditor with Ia5e9767e08.
The heightExtension in the CodeMirror class still remains, in the event
a subclass wishes to override the default behaviour in CM directly and
not with CSS.

It is necessary to have a way to toggle CodeMirror on and off, so we use
WikiEditor and hide all other buttons. This is more costly than loading
just vanilla CodeMirror, but it ensures a consistent experience with
pages that are editable, with the toggle button in the familiar place.
At a later time, WikiEditor may be updated to better support read only
pages in a lightweight fashion (T188817).

The ResizingDragBar makes the editor resizable, so we need to set the
CodeMirror height to 100%. This only happens when the Realtime Preview
module is loaded.
This fixes a critical issue introduced by I4deeda192b that caused blank
renderings when scrolling large documents.

Add a new $wgCodeMirrorV6 temporary feature flag that when enabled,
will load the 'ext.CodeMirror.v6.WikiEditor' module that is built
against CodeMirror 6. You can also pass in the ?cm6enable=1 query
parameter to force use of CodeMirror 6. This is currently only
implemented for the 2010 editor.
Due to packaging constraints with CodeMirror 6, we now use Webpack to
bundle the files, which are then used by ResourceLoader. This is similar
to what is done for Extension:Popups, MobileFrontend, among other
extensions.
A new generic class CodeMirror can be used on other areas where syntax
highlighting is desirable, but not necessarily for editing (i.e. without
WikiEditor).
This commit merely lays the foundation for CodeMirror 6 and updates
WikiEditor to use it. The actual MediaWiki syntax highlighting will come
with a future commit.
With the new Webpack build, the Gruntfile was removed and the tasks
moved to npm commands.
