SOLR-8306: Optimize expand.rows=0 to compute only total hits (#1334)

* When expand.rows=0, expand documents are not returned. So, computing them 
could be avoided and only total hits need to be computed

> Enhance ExpandComponent to allow expand.hits=0

> This enhancement allows the ExpandComponent to allow expand.hits=0 for those 
> who don't want an expanded document returned and only want the numFound from 
> the expand section.
> This is useful for "See 54 more like this" use cases, but without the 
> performance hit of gathering an entire expanded document.
