Drill 2274: Unable to allocate sv2 buffer after repeated attempts : JOIN,
Order by used in query
main improvements are:
- when external sort cannot allocate a new SV2, it spills
`spilledBatchGroups` and not `batchGroups` to make sure it frees memory from
the sort's allocator
- `copierAllocator` is closed as soon as possible to make sure more memory
is available for the sort
