LUCENE-8609: Allow getting consistent docstats from IndexWriter
Today we have #numDocs() and #maxDoc() on IndexWriter. This is enough
to get all stats for the current index but it's subject to concurrency
and might return numbers that are not consistent ie. some cases can
return maxDoc < numDocs which is undesirable. This change adds a
getDocStats()
method to index writer to allow fetching consistent numbers for these stats.
