refactor(buildimage): 重构 Registry 结构体并添加新方法

- 在 Registry 结构体中添加了 GetManifestList 和 PushManifest 方法
- 修改了 SaveImages 方法的实现，移除了 SaveRegistryImages 方法
- 更新了 replaceManifestWithSingleArch 方法，使用 types.Manifest 替代 v1.Manifest
- 在 image/build.go 中更新了 applyRegistryToImage 方法的调用，使用 SaveImages 替代 SaveRegistryImages
