LUCENE-10252: ValueSource.asDoubleValues should not compute the score (#519)
ValueSource.asDoubleValues and asLongValues should not compute the score unless
asked to -- typically never. This fixes a performance regression since 7.3
LUCENE-8099 when some older boosting queries were replaced with this.
> ValueSource.asDoubleValues shouldn't fetch score

> The ValueSource.asDoubleValuesSource() method bridges the old API to the new
> one. It's rather important because boosting a query no longer has an old
> API; in its place is using this method and passing to
> FunctionScoreQuery.boostByValue. Unfortunately, asDoubleValuesSource will
> fetch/compute the score for the document in order to expose it in a Scorable
> on the "scorer" key of the context Map. AFAICT nothing in Lucene or Solr
> actually uses this. If it should be kept, the Scorable's score() method
> could fetch it at that time (e.g. on-demand).
