Fix `Lucene104HnswScalarQuantizedVectorsFormat` merges with an asymmetric encoding (1 and 2 bit quantization today) and `COSINE` similarity: the merge scorer's query side was quantized from un-normalized vectors while the index side was normalized, so the merge trips an assertion and otherwise builds the graph from wrong scores.
(cherry picked from commit 8ece74d1e2103f6fdb0788162e9b3a826b499dec with minor adaptations for 10.x)
