[I] Remove COMET_SHUFFLE_FALLBACK_TO_COLUMNAR config [datafusion-comet]

andygrove opened a new issue, #1254:
URL: https://github.com/apache/datafusion-comet/issues/1254

   ### What is the problem the feature request solves?
   
   https://github.com/apache/datafusion-comet/pull/1209 enabled accelerating more queries with Comet but also exposed some new bugs so a COMET_SHUFFLE_FALLBACK_TO_COLUMNAR config was added as a temporary workaround to avoid Spark SQL tests failing.
   
   We should remove this config once the bugs are fixed so that we test more of the Spark SQL queries with Comet shuffle.
   
   ### Describe the potential solution

   Barring AQE and DPP tets ( addressed in a different PR https://github.com/apache/datafusion-comet/pull/1811 ) , I am able to run these tests successfully . Not sure if this is still an issue @andygrove  ?

   The tests are still failing in CI in https://github.com/apache/datafusion-comet/pull/1736

   I removed the following from the scope of this issue since they turned out not to be bugs or correctness issues, but valid failures because Comet does not support DPP natively yet.
   
   - SPARK-34637: DPP side broadcast query stage is created firstly *** FAILED *** (235 milliseconds)
     - https://github.com/apache/datafusion-comet/issues/1839
   - avoid reordering broadcast join keys to match input hash partitioning *** FAILED *** (1 second, 659 milliseconds)
