[mm-kgi]

Summary

This PR introduces ARM64 Docker image build and publishing support for the DPP Plugin CI/CD pipeline.

Using Docker Buildx, the pipeline now produces multi-architecture Docker images that support both AMD64 and ARM64 deployments while maintaining existing pipeline behavior.

Changes

• Added Docker Buildx configuration
• Enabled multi-platform builds for:
  • linux/amd64
  • linux/arm64
• Configured multi-architecture manifest creation
• Added ARM64 image publishing using existing project tagging conventions
• Added manual ARM64 build trigger capability
• Ensured security scans execute against ARM64 images
• Documented ARM64 build performance investigation and selected deployment strategy
