compact separate for gc referencer (#533)

- Refactor GCV2 so GcReferencer::RemoveExpiredData returns a store compactor, moving out the actual disk work from deleting items in the index.
- Refactor GCV2 GcResult to reuse GcCompactStoreStats and GcStats
- Make Compacting of stores non-parallell to not eat all the disk I/O when running GC
