Make nydus image more compatible with OCI

2

A personal idea by @hsiangkao, but I agree with the point. 1. Allow ctr/crictl/nerdctl pull directly without nydus snapshotter; 2. Use `zstd:chunked/estargz` compression algorithm for blob layer; 3. Allow lzay...

This issue is to track [the buildkit PR](https://github.com/moby/buildkit/pull/2581) With the above support, one can build a nydus image with buildkit directly.

We need a detailed document on the nydus image format, focusing on: 1. The manifest format 2. Rafsv5 bootstrap+blob format 3. Rafsv6 bootstrap+blob format

There is a slightly shared-bitmap implementation in [the persist_map code](https://github.com/dragonflyoss/image-service/blob/master/storage/src/cache/state/persist_map.rs). It can be generalized into a library crate that might be useful for other projects.
