This series extends sstable cleanup to resharding and other (offstrategy, major, and regular) compaction types so to:
* cleanup uploaded sstables (#11933)
* cleanup staging sstables after they are moved back to the main directory and become eligible for compaction (#9559)
When perform_cleanup is called, all sstables are scanned, and those that require cleanup are marked as such, and are added for tracking to table_state::cleanup_sstable_set. They are removed from that set once released by compaction.
Along with that sstables set, we keep the owned_ranges_ptr used by cleanup in the table_state to allow other compaction types (offstrategy, major, or regular) to cleanup those sstables that are marked as require_cleanup and that were skipped by cleanup compaction for either being in the maintenance set (requiring offstrategy compaction) or in staging.
Resharding is using a more straightforward mechanism of passing the owned token ranges when resharding uploaded sstables and using it to detect sstable that require cleanup, now done as piggybacked on resharding compaction.
Closes#12422
