Beyond @stevenh's review which I concur with, I'd like to see this PR use string-specs for the platform (like the rest of the TC/Docker API) and use github.com/containerd/platforms.ParseAll() to transform them.

For reference, we addressed this in the go-sdk too: https://pkg.go.dev/github.com/docker/go-sdk/image#SaveOption |

What does this PR do?
This introduces a way to pass image save options (like platform) to the image client. This allows saving a specific architecture for an image.
Why is it important?
With OCI multi-arch images, it is sometimes needed to save image for a different architecture than the current one. This changes allows to control the behavior instead of defaulting to the current platform.
