Timo Tijhof b843094a2d Re-implement and improve mw-jump links with pure CSS
* Improve their accessibility by giving both links
  a full label "Jump to x" and "Jump to y" instead
  of "Jump to: ", "x", "y".

  This also makes things much better for localisation, for which
  we generally discourage use of concatenation.

* Use pure CSS for the toggling of the visibility on focus,
  instead of relying on JavaScript. Especially given the
  JS comes form core's 'jquery.mw-jump' module, which is
  considered technical debt per T195256. Alternatively,
  that could be copied to vector.js, but pure CSS
  is possible, so why not.

* Use plain <a> links in the HTML instead of wrapped in a <div>.
  This solves the long-standing problem whereby the margin
  between #contentSub and #mw-content-text had to be awkwardly
  negated and overridden in core and on various to make sure that
  the wrapper itself would become visible as needed, in a way that
  has margin around this. This whole problem doesn't apply when
  simply using inline links that aren't part of the regular flow
  with .mixin-screen-reader-text. On focus, the individually
  focussed link appears in regular flow, without the need for
  any custom styles.

* This uses :not(:focus) to naturally make it render in the default
  way on focus, and visibibly hidden/clipped otherwise.
  This is supported in IE9+ and Android 2+.
  There is a way to make it work with CSS2 for IE7-8, by applying
  the mixin to '.mw-jump-link' only and then undoing all of
  'position', 'width', 'height', 'clip', and 'margin' on :focus.
  But I'm not sure that's worth it here. The fallback in IE7-8
  for not supporting ":not(:focus)" is that the accessibility
  link is simply visible always, which seems like a good fallback
  for accessibility, and doesn't hurt anything.
