SOLR-16162: FilterQuery should implement DocSetProducer
See: SOLR-16162
"producing a DocSet" is what FilterQuery is actually doing anyway; but more important practically: this avoids the cloning of the backing query's DocSet (and the creation of superfluous DocSets).
As described in the jira and here, the description and fix seems reasonable to me. I just don't know the code well enough in this part to say if this should go in.
Pending feedback/objections, I plan to merge this in the coming week.
ha, thanks for noticing this one. I guess I missed the "coming week" window by more than a year 😅 . I'll take care of this shortly.
