IMPALA-15184: Switch tpcds json from bzip to zstd

bzip is very slow, and it is enough to test it on
smaller data (already covered in functional text).
Switching to zstd, which did not have its own db.

From dataload logs before change:
Loading TPC-H data OK (Took: 5 min 39 sec)
Loading TPC-DS data OK (Took: 22 min 33 sec)
Loading functional-query data OK (Took: 30 min 43 sec)

After change:
Loading TPC-H data OK (Took: 5 min 22 sec)
Loading TPC-DS data OK (Took: 13 min 49 sec)
Loading functional-query data OK (Took: 27 min 30 sec)

Total dataload time is decreased from ~35m to ~30m.

The longest leg functional-query also decreased, likely
due to less contention on the max 2 parallel Hive queries
(see IMPALA-15185 for details on Hive parallelism).
