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.
