LUCENE-8599: Use sparse bitset to store docs in SingleValueDocValuesFieldUpdates
Using a sparse bitset in SingleValueDocValuesFieldUdpates allows storing
which documents have an update much more efficient and prevents the need
to sort the docs array altogether that showed to be a significant bottleneck
in LUCENE-8598. Using the spares bitset yields another 10x performance improvement
in applying updates versus the changes proposed in LUCENE-8598.
