[PR] chore: Add primary key constraints for TPC-H, TPC-DS [datafusion]

["neilconway (via GitHub)" <gi...@apache.org>]

neilconway opened a new pull request, #22646:
URL: https://github.com/apache/datafusion/pull/22646

   ## Which issue does this PR close?
   
   - Closes #22595.
   
   ## Rationale for this change
   
   The TPC-DS and TPC-H specifications define primary keys, but we previously did not include those constraints when defining the TPC-DS and TPC-H schemas. Including the constraints enables the query optimizer to generate better plans (e.g., by leveraging FDs); it also makes the benchmark setup closer to a realistic TPC-DS/H benchmark run.
