[CICD][MIRROR][AZURE] Add Azure-hosted mirror for Yocto packages

Some upstream Yocto packages may become unavailable for various reasons, causing build failures in CI/CD pipelines, developer environments, and customer systems. Introducing a mirrored repository ensures package availability, mitigating risks from upstream discontinuations and improving build reliability.

This commit introduces a sync script for uploading Yocto packages to Azure Blob Storage, ensuring consistent package availability. It also configures DL_DIR to use a separate folder, allowing packages to be collected in a dedicated pipeline stage responsible for syncing.
