[PR] test: cover lpad and rpad routing configurations [datafusion-comet]

rich7420 opened a new pull request, #5895:
URL: https://github.com/apache/datafusion-comet/pull/5895

   ## Which issue does this PR close?
   
   Part of #4616.
   
   ## Rationale for this change
   
   The `lpad` and `rpad` tests do not verify routing with the codegen dispatcher disabled. Their global dispatcher counters also do not identify which expression ran.
   
   ## What changes are included in this PR?
   
   Check both dispatcher settings in the existing tests. Supported argument shapes must stay native; unsupported shapes must dispatch or fall back with the disabled-dispatcher reason. Replace global counters with expression-specific assertions and remove the redundant `allowIncompatible` loop.
   
   ## How are these changes tested?
   
   All four routing tests pass locally on Spark 4.1 after rebasing, covering 20 query/configuration combinations and comparing results with Spark. Injected routing regressions are caught for both expressions.
   
   [Fork CI](https://github.com/rich7420/datafusion-comet/actions/runs/34691737704) passed before the rebase and configuration-loop cleanup. CI for the revised head is pending.

   > Thanks @rich7420. Maybe we could just delete these tests and re-implement in the Comet SQL suite?
   
   sure, I'll try to do that

   Thanks @rich7420. Maybe we could just delete these tests and re-implement in the Comet SQL suite?
