[CK_TILE] Fix for Moving DataTypeTraits into a Common File (#3335)

This PR fixes a mismatch caused when PR #3146 was merged out of sync with develop, which made its intended changes ineffective. This PR reapplies those changes to move DataTypeTraits into a common file to mitigate code duplication.
