Since WT-9631, compaction can produce this progress message:

compacting collection-45-12116826515201326078.wt for 35 seconds; reviewed 97544 pages, rewritten 7995 pages (7MB), approx. 100% done

Despite this log and the "100% done", compaction may continue on the collection if there is more work to do. The progress is derived as shown below:

            progress = WT_MIN(
              (int)(100 * block->compact_pages_rewritten / block->compact_pages_rewritten_expected),
              100);

Because compaction may rewrite more than what was estimated, this log may keep appearing with "100% done" while compaction is still working. The goal of this ticket is to improve this message to avoid any confusion.
