This is a technical task product of Implement clay:row tag which goal is to replace existing usages of aui:col by clay:col.
- There are no `aui:col` usages left in jsps in DXP
- The resulting markup output after the change either:
- Remains unchanged (when the markup was correct)
- Is updated to correct markup (when it was legacy)
Note: Only usages in modules/apps need to be updated. Usages in archived, portal-web, util-taglib, modules/sdk... can be left as they are.
