Subject: [PATCH] Include additional analytics in Special:Search

* Adds query performed to javascript config, to be picked up by
  the TestSearchSatisfaction schema.

* Adds data-serp-pos attribute to serach result anchors.
  This is picked up by the TestSearchSatisfaction schema
  and appended to urls (when participating in the test)
  as the `wprov` query parameter.
