Review Comment:
Background:
https://github.com/apache/lucene/issues/12659#issuecomment-1759244758
This was a try to get back the PKLookUp speed but Luceneutil has shown that
this change does not affect performance. I kept it here because I think this
way is more consistent with the `DataInput#readVInt` and more readable. But now
I would revert it since it is not really related to the point of this PR.
