Simon Willnauer 98fd45dc02 Move DocStats under Engine to get more accurate numbers (#18587)
Today we pull doc stats from an index reader which might not reflect reality.
IndexWriter might have merged all deletes away but due to a missing refresh
the stats are completely off. This change pulls doc stats from the IndexWriter
directly instead of relying on refreshes to run regularly. Note: Buffered deletes
are still not visible until the segments are flushed to disk.
