Enable multi-platform (amd64/arm64) Docker image building using docker buildx. This allows building and pushing images for both x86_64 and ARM64 architectures simultaneously. Changes: - Update Makefile to use docker buildx for multi-platform builds - Add PLATFORMS and PUSH variables to control build behavior - Update build documentation in README files (en/zh/ko) - Fix deprecated ENV format in Dockerfile By default, PLATFORMS is set to "linux/amd64,linux/arm64" and PUSH is false. When PUSH=true, the build command will push the multi-arch manifest directly to the registry. Change-Id: I51a256e7cf8c70f3ab42cf72b6f423989dd902da Signed-off-by: Wu Wenxiang <wu.wenxiang@algoblu.com>
