LUCENE-8608: Extract utility class to iterate over terms docs
Today we re-implement the same algorithm in various places
when we want to consume all docs for a set/list of terms. This
caused serious slowdowns for instance in the case of applying
updates fixed in LUCENE-8602. This change extracts the common
usage and shares the interation code including logic to reuse
Terms and PostingsEnum instances as much as possble and adds
tests for it.
