Issue #, if available:
N/A

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

Changes:

• Add resizePolicy field to values.yaml (default: [])
• 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
    restartPolicy: NotRequired
  - resourceName: memory
    restartPolicy: RestartContainer

How you tested your changes:
Environment (Linux / Windows): Linux (Amazon Linux 2023)
Kubernetes Version: 1.34

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

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