This commit updates the injected stats for the TPC-C and TPC-H stats quality tests to include multi-column stats. Since multi-column stats are currently only used by the optimizer in a few limited cases, none of the plans changed. This commit is in preparation for work that will be done in the optimizer to use multi-column stats for selectivity estimation. Informs cockroachdb#34422 Release note: None
