This is a re-submit of #90150 which was reverted by #90815

Changelog category (leave one):

• Backward Incompatible Change

Changelog entry (a user-readable short description of the changes that goes into CHANGELOG.md):

Changed the default of setting check_query_single_value_result from true to false. This causes CHECK TABLE to return detailed per-part results instead of an aggregated result (1 = okay, 0 = errors found). Compared to the previous behavior, this is likely more aligned with what the user wants.
