feat: Adding Pod Identity / Access Entries option for Karpenter

[rodrigobersa]

What does this PR do?

Enables Pod Identity and Access Entry feature for Karpenter addon.

• Adding variable to create Karpenter access entry.
• Changed the tests/complete
  • Use Pod Identity provided by the https://github.com/aws-ia/terraform-aws-eks-blueprints-addon module.
  • Adding Pod Identity Addon
  • Adding tags for Karpenter discovery
• Updating Karpenter namespace to kube-system, as recommended since v0.33

TO DO: Change the "aws-ia/eks-blueprints-addon/aws" to the version supporting Pod Identity, pre-commit checks will not pass without that.

Motivation

Pod Identity and Access Entries aims to be the default options for granting permissions to addons. We should adopt this in the v2.
