   ### What problem does this PR solve?
   
   This PR adds support for spill repartition in partitioned operators.
   
   When memory is still insufficient after a partition has been spilled, the 
spilled partition can be repartitioned into smaller sub-partitions, which 
further reduces peak memory usage. The repartitioner is made level-aware so 
repartition can be applied recursively when needed.
   
   This PR also integrates the new spill repartition flow into partitioned hash 
join and partitioned aggregation, adds force-spill logic in the join sink 
operator, refactors spill file interfaces, improves spill metadata maintenance 
and memory-pressure handling, and fixes several spill-related issues such as 
revocable memory accounting and profile updates.
