feat(v2): GraalVM support for Batch Processing utility

[phipag]

This issue tracks adding GraalVM support to the Batch Processing utility.

Please follow guidance for the parent issue: #1818

We have a guide for adding GraalVM support to a utility: https://github.com/aws-powertools/powertools-lambda-java/blob/7f604e4c67d838d6f72ad340c5f4af7492f1e624/GraalVM.md

I'll try to pick this up.

Awesome! Thanks @jreijn, you know the drill already! :-D

Ideally, we create an example to test this end-to-end again similar to what you did with the Parameters utility. We have an example for batch processing using SAM here: https://github.com/aws-powertools/powertools-lambda-java/tree/v2/examples/powertools-examples-batch
