Add support for ARM-based GPU instance types

[mmasaki]

What would you like to be added:
Add support for arm64 instances with GPU.
G5g instance type is released: https://aws.amazon.com/jp/ec2/instance-types/g5g/

Why is this needed:
To use G5g instances in EKS

I'm going to close this, as the max pod definitions now include:

g5g.16xlarge 737
g5g.2xlarge 58
g5g.4xlarge 234
g5g.8xlarge 234
g5g.metal 737
g5g.xlarge 58

Re-opening because we haven't actually shipped a GPU AMI that has this support; though custom AMI builders are able to leverage the max pod definitions.

Any updates on this?

@mmasaki as an alternative path, I've managed to run g5g instances with GPU support by running the Ubuntu ARM AMI alongside the nvidia-gpu-operator. It's a bit more complex, but will work until we get an official Accelerated AL2 ARM AMI

@cartermckinnon has the priority on this shifted with the AL 2023 work/other general refactors going on right now with the EKS AMI repo?

Any updates on potential release date?
