RTL rules within and around the content need to apply to the content
language, not the interface language, so we want to disable the normal
CSSJanus auto-flipping.

I74bcbc46b0 erroneously passed the model's directionality (how it is
saved) and not the view. This caused misalignment issues when changing
directionality.

This fixes a bug in the 2017 editor implementation where changes to the
gutter width were calculated before the gutter element was updated.
This fix prevents misalignment issues when copying and pasting large
amounts of content.

This was introduced in Iac30ffe274 to control the rollout of CM6 to RTL
wikis separately from LTR wikis because of various bugs. While RTL still
isn't perfect, it is stable enough now (hewiki has not complained) and
the 2017 editor is also fully supported. Thus, we no longer need this
feature flag.

The 2017 editor has an infinite viewport, meaning the entire document is
printed on page load. CodeMirror 6 meanwhile only processes text in the
visible viewport. This presents a situation where if large chunks of
text are inserted outside the visible range (such as the "Changes
recovered" feature of VE), it can cause misalignment of the VE surface
and visible CodeMirror layer, as CodeMirror has not accounted for the
off-screen lines of text.
CodeMirror 5 had a `viewportMargin: infinity` option that prevented this
issue, but at the cost of performance. CodeMirror 6 removed this option,
but the same effect can be achieved by tricking CodeMirror into thinking
we're printing the document, in which case it will process all lines.
This seriously hurts performance, and is a nasty hack, but until the
2017 editor is reworked to have a viewport, there may be no other means
to prevent the misalignment.

Add new temporary ext.CodeMirror.visualEditor.init RL module which
selects the temporary ext.CodeMirror.visualEditor.v6 or non-v6 based on
$wgCodeMirrorV6. This will allow us to deploy CM6 further.
As a result of this work, the core CodeMirror class now has knowledge
of ve.ui.Surface.
Other changes:
* Add Compartment for specialCharsExtension so it can be disabled in VE.
* Add option to mediaWikiLang() to disable template folding.
* Add support for RTL wikis where $wgCodeMirrorRTL is enabled.
* Make CodeMirror.logUsage() and setCodeMirrorPreference() static.
* Fix unit and linting tests.
