Follow up from random datagen seed PR

If you are looking at these, the way to override the seed is via: SPARK_RAPIDS_TEST_DATAGEN_SEED.

As a follow on for #9441, I added:

• [BUG] test_in_set fails when DATAGEN_SEED=1698940723 #9687
• [BUG] test_case_when fails with DATAGEN_SEED=1698940723 #9685
• [BUG] test_coalesce fails with DATAGEN_SEED=1698940723 #9684
• [BUG] test_map_scalars_supported_key_types fails with DATAGEN_SEED=1698940723 #9683
• [BUG] Casting FLOAT64 to DECIMAL(12,7) produces different rows from Apache Spark CPU #9682
• [BUG] test_ts_formats_round_trip and test_datetime_roundtrip_with_legacy_rebase fail with DATAGEN_SEED=1699915317 #9701
• [BUG] test_cast_string_ts_valid_format fails with DATAGEN_SEED=1699978422 #9708
• [BUG] test_lte fails with DATAGEN_SEED=1699987762 #9711
• [BUG] test_floor_scale_zero fails with DATAGEN_SEED=1700009407 #9722

After we merged datagen change, we found:

• [BUG] Integration test test_re_replace_all fails with a corner case #9731
• [BUG] test_delta_part_write_round_trip_unmanaged and test_delta_multi_part_write_round_trip_unmanaged fail with DATAGEN_SEED=1700105176 #9738

This issue groups the above.

Issues are closed. The remaining issue #9731 is a corner case that will be handled separately.
