Workbench: Implement a more deterministic solution for validating COType

[sharadsw]

Follow-up to #6194

As a quick fix, COType validation uses a naive approach of figuring out the COType value in a given row. It fetches the cotype column based on string matching but there could be scenarios where this is too simplistic. This can be improved upon by sending a parameter to ScopedTreeRecord which indicates which column to look at for COType, ideally obtained from parsing the rest of the dataset prior to this.
