LUCENE-10408 Better encoding of doc Ids in vectors (#649)
Better encoding of doc Ids in Lucene91HnswVectorsFormat
for a dense case where all docs have vectors.
Currently we write doc Ids of all documents that have vectors
not very efficiently.
This improve their encoding by for a case when all documents
have vectors, we don't write document IDs, but just write a
single short value – a dense marker.
