Support for clusters with trn1 instance types

[dewjam]

Description

Per #5896, TRN1 instance types are now available in us-west-2 and us-east-1. This PR ensures Trn1 instance types will be launched with the EKS Accelerated AMI by default and also will install the Neuron Device Plugin by default. This also upgrades the Neuron Device Plugin to version 1.9.3.0 2.1.2.0 which is required for Trn1 support.

Example:

./eksctl create cluster \
    --name trainium \
    --region us-west \
    --zones us-west-2b,us-west-2d \
    --nodegroup-name trainium-2 \
    --node-type trn1.2xlarge \
    --node-zones us-west-2d \
    --nodes 1 \
    --nodes-min 1 \
    --nodes-max 4 \
    --ssh-access \
    --with-oidc

Hey @Himangini
Tests should be fixed and I also rebased against main. Any chance I can get another review?

[cPu1]

I have left some comments for improving the validation and the integration tests.

[dewjam]

Updated tests. This is ready for review again. Thanks!

[cPu1]

LGTM!

[dewjam]

Curious, is map[string]struct{}{} a style thing? Or is it more efficient than map[string]bool for this case?

[cPu1]

It's more efficient, takes fewer bytes, and is more idiomatic when you're using a map as a set.
