Add resizePolicy option to the Helm chart to support Kubernetes In-Place Pod Vertical Scaling feature.

Changes:

• Add resizePolicy template block to deployment.yaml, daemonset.linux.yaml, and daemonset.windows.yaml
• Update README.md with resizePolicy parameter documentation

Example usage:

resizePolicy:
  - resourceName: cpu

Tested with helm template to verify the resizePolicy is correctly rendered:

./config/helm/aws-node-termination-handler \
  --set resizePolicy[0].resourceName=cpu \
  --set resizePolicy[0].restartPolicy=NotRequired
