Speed up TestIndexOrDocValuesQuery. (#12672) 

This changes the following:
 - fewer docs indexed in non-nightly runs,
 - `QueryUtils#checkFirstSkipTo` uses the `ScorerSupplier` API to convey it
   will only check one doc,
 - `QueryUtils#checkFirstSkipTo` no longer relies on timing to run in a
   reasonably amount of time.
