Review Comment:
   > This change may not ensure CI passes.
   Why?
   @cxzl25  ,  CI UT failures are triggered by codegen at 
`DeserializeToObjectExec.$anonfun$doExecute$1(objects.scala:95)` – this part is 
not controlled by `spark.sql.codegen.xxx` configs, so setting these params 
specifically for Spark 4.1 has no effect.
   
   The odd thing is: Spark 4.1 CI UTs pass fine if we globally disable codegen 
via `spark.sql.codegen.xxx` for all CI UTs.
