IMPALA-9126: part 4: hash join builder manages spilling

This is the final patch for IMPALA-9126.

This will allow the many:1 relationship of probe:build
partitions that we need for the shared join build.

Key changes:
* Builder picks the next spilled partition to process.
* Partitions are identified by unique ID so can be
  decoupled between build and probe.
* unique_ptr is used to manage build partitions. This
  helps document the lifecycle of the partitions better,
  particularly when they are handed off to
  PartitionedHashJoinNode.

Testing:
* Ran exhaustive tests.
* Ran a single node TPC-H and TPC-DS stress test with 1000 queries.

Perf:
Ran a single node TPC-H 30 test against master from
before IMPALA-9126 changes. No significant perf
change.
