ci: add script to upload build artifacts to Cloudsmith

  Add prepare_artifacts_for_cloudsmith.sh which:
  - Organizes kernel images and DTBs by architecture/platform
  - Generates git properties file with branch and commit info
  - Uploads artifacts to Cloudsmith using wiki-scripts utility
  - Sets Azure pipeline variables for downstream stages

  Called from azure-pipelines.yml in the Publish_to_Cloudsmith job.
