Consider enabling disk spill encryption by default

    Description

      We currently have integrity checks disabled by default because of the additional CPU cost.

      Now that IMPALA-6219 is in, the integrity checks are cheaper so it may be worth just paying the cost. We could also consider doing a lighter-weight CRC checksum, but AES-GCM may be fast enough at 2.3GB/s to do by default.

      We should do an experiment to see if there's a major impact on spill-to-disk perf.
