Expose SameElement query terms to ranking.

A TermFieldMatchData is allocated per SameElement term,
and this is used to signal matching docids in doUnpack() on the SameElement search iterator.
This allows using the matches() rank feature on a field (virtual) that is searched using a SameElement term.
