[I] Comet falls back to Spark for final hash aggregate in some cases when it could be supported [datafusion-comet]

andygrove opened a new issue, #2894:
URL: https://github.com/apache/datafusion-comet/issues/2894

   ### What is the problem the feature request solves?
   
   Comet currently tries to avoid mixing "Spark partial / Comet final" and "Comet partial / Spark final" aggregates. This is necessary in some cases due to incompatibilities between Spark and Comet for the intermediate aggregate buffer format, but in other cases this fallback is not necessary.
   
   ### Describe the potential solution
   
   Add logic to determine which aggregates are safe to have both Spark and Comet operators and do not fall back for those.
   
   ### Additional context
