…lure. Fixes NVIDIA#10134. This commit fixes test failures in `test_window_aggs_for_batched_finite_row_windows_partitioned`, resulting from ambiguous ordering in the window function input. The failing tests partition by `a`, and order by `b,c`. When the values of `b,c` have repeated values, the results from the window function execution is indeterminate. This commit changes the definition of the aggregation column `c` (that's also included in the order-by clause), to use unique long values. This guarantees deterministic output.

@mythrocks are there major performance issues with these tests? CI timed out, and I see a huge time gap while running what looks like related tests. From the premerge log: |

No, no performance issues of which I'm aware. I'll double-check locally. Edit: These both run end-to-end in about 20 seconds locally. |

Fixes NVIDIA#10195. This is similar to the fix in NVIDIA#10143. This commit changes the test datagens used in the window function tests such that the order-by columns produce deterministic ordering. When the ordering is ambiguous, it can produce unexpected results from window functions, if the `order-by` spec includes the ambiguous columns. Signed-off-by: MithunR <mythrocks@gmail.com>
