Adds AZL4 build pipeline stages with MCR-hosted MIC container, BlobImageManifest class for ACG blob source downloads, and service connection runbook. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
testimages.py runs docker with the short tag (imagecustomizer:1.4.0-1) but docker pull uses the full MCR path. Without a local tag, docker run fails with 'pull access denied'. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
AZL4 base VHDXes may continue to come from blob storage rather than the ADO feed. The trident-service RPM will come from an AZL4 package repo, not ADO. Update comments to reflect this. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Summary
Adds the CI pipeline infrastructure to build AZL4 test images: base VHDX acquisition from the AZL preview gallery, MIC container from MCR, blob download tooling, and the AZL4 build pipeline stages.
Part 4 of the AZL4 enablement stack. Depends on PR #679 (BLS entry support).
