Enable processing and/or memory optimized instances when using sagemaker.remote_function's @remote decorator

**Describe the feature you'd like**
Currently only training instances are allowed when using @remote (from the sagemaker.remote_function module). This module can be used for processing tasks as well, so it would be useful to have more instance types available.

**How would this feature be used? Please describe.**
Using instances with more than 256GB that don't need GPU acceleration for processing tasks. These are only available as Processing instances as far as I know (and are referred as Memory optimized instances there).

**Describe alternatives you've considered**
We can use Sagemaker Processing jobs, and we currently do that. The downside is that local mode is not enabled when using Sagemaker studio, so it can be a little clunky to develop scripts locally before submitting then to a processing task. This is much easier when using @remote, since we can execute code directly without the need of mapping inputs/outputs, etc. Code for local testing and remote execution could be very similar if not identical in this case.

**Additional context**
In case this is not clear, I'm referring to this functionality: https://docs.aws.amazon.com/sagemaker/latest/dg/train-remote-decorator.html

Commencez par le module sagemaker.remote_function et son décorateur @remote, puis comparez les types d’instances acceptés avec la documentation SageMaker du décorateur remote indiquée dans l’issue. La tâche est terminée lorsque @remote prend en charge les instances de traitement et optimisées pour la mémoire pour les tâches de traitement, tout en préservant le comportement d’entraînement existant ; ajoutez une couverture ciblée si le dépôt contient des tests pertinents.
