add loongarch64 support for archutil

[yzewei]

The LoongArch architecture (LoongArch) is an Instruction Set Architecture (ISA) that has a RISC style.

I'm not sure if we want to include this in regular release as it does add overhead to detect these architectures that are rarely used. Maybe with a special go build tag?

Thank you for your suggestions and reminders. I have recently provided Loongarch adaptation for Buildkit, in order to complete the work of building mirrors cross -architecture on Loongarch
Based on your previous reply, I recently provided Loongarch support for the xx project
I do n’t understand what you said to add a special Go Build label. I use xx-go after the xx project is transplanted?

@yzewei Needs rebase related to changes from #4607. This should kick ci and validate archutil.

EDIT: rebased myself and pushed changes.

@yzewei Seems aarch64 package does not exist from previous comment, see: https://github.com/moby/buildkit/actions/runs/7868985167/job/21467181513?pr=4392#step:5:252

You can try locally with docker buildx bake validate-archutil --set "*.platform=linux/arm64"

Sorry, you are right. The debian image in the arm architecture does not have this toolkit. What else do I need to do?
As the debian community improves its support for the loongarch architecture, more architecture support should be added in the future, such as aarch64
Can we currently only verify the amd64 architecture and temporarily block the arm64 architecture?
