Change subject: tablet: plumb delta stats into delta compaction outputs

tablet: plumb delta stats into delta compaction outputs
This plumbs delta stats from a delta compaction into the delta tracker's
call to open the output delta readers. This means that in-memory delta
stats aren't "lost" when doing a delta compaction, and that we can GC
ancient deleted rowsets after a delta compaction without reading the
stats from disk.
I considered also plumbing stats into merge compaction outputs, but
opted not to. The plumbing for compactions seems more significant, and
chances are, large bulk deletes will come after data has had time to be
compacted (e.g. deleting old ranges of keyspace).
