Move this stuff to Timeless itself since we can just reuse the width cutoff
and padding variables directly there and don't need to worry about them
randomly changing.

VisualEditor's default padding for the source editing surface was
changed in Icdc6f1e2a7544ebbd828f85ff370113a0e06983a (June 2018).
Since then the alignment of editing surface and CodeMirror syntax
highlighting surface was broken in skins that don't override the
default padding (basically every skin except Vector and MonoBook).
Unfortunately Vector and MonoBook happen to be the only skins we
officially support and actually test, so the issue went unnoticed.

Keep all our font rule settings in one place to make it
easier to keep them in sync. Also add a rule for 'hyphens' in
case the browser default has changed.

We can't guarantee the preserve glyph width, e.g.
on Firefox with Chinese characters.

CM surface is just for presentation, it shouldn't
be possible to focus or select anything in the surface,
so in addition to it being beneath the VE surface,
disable it through the CM API and disable pointer-events
with CSS.

Long-term todo:
* Performance will be poor on large pages due
to using a auto-height textarea which CodeMirror
doesn't optimise.
