[I] Use unified memory management for Comet [datafusion-comet]

viirya opened a new issue, #1017:
URL: https://github.com/apache/datafusion-comet/issues/1017

   ### What is the problem the feature request solves?
   
   We currently only enable unified memory manager for Comet if off-heap mode is enabled. It causes some memory issues like #996, #949, etc.
   
   Re-thinking about this, I think a better approach is to use unified memory management for Comet, i.e. off-heap mode must be enabled for Comet. It could simplify memory management in Comet. It can give a more explicit signal to users that off-heap memory is used for Comet native execution that should give users a more clear picture about how Spark/Comet memory is used (so they don't need to guess).
