To give a bit more context about why I ended up adding
`ScorerSupplier#setTopLevelScoringClause`: I considered other options, such as:
- adding a new `ScoreMode` but `Query#createWeight` is too early to make
this kind of decision. E.g. if your query is `a OR b`, `a` may be the top-level
scoring clause if `b` produces a null scorer, so `createWeight` is not a good
fit.
- adding a new parameter to `Weight#scorer`, but again it's too early for
the same reason. With query `a OR b`, if Lucene creates a scorer for `a` first
assuming it will be a clause of a boolean query, but if then `b` produces a
`null` scorer, `a` will be the top-level scoring clause, but it's already been
created as a non-top-level scoring clause.
- adding a similar `setTopLevelScoringClause` on `Scorer`, but I did not
like mutating scorers
So a setter on `ScorerSupplier` felt like the best place to set this kind of
information.
