Support --artifact-platform in oras attach?

[Wwwsylvia]

In #1066, we discussed adding platform information into the artifact manifest. Now we have implemented the --artifact-platform flag for oras push, we should also consider if it's helpful to add the same functionality to oras attach.

It would be something like:

oras attach localhost:5000/oras:v1.0.1 --artifact-type "application/vnd.sbom" --artifact-platform linux/amd64 oras--1.0.1.arm64_monterey.bottle.tar.gz

It may require a valid scenario to justify why platform information is necessary for a referrer artifact. Suggest keeping this issue open for discussion and feedback gathering from the community.

well consider attaching platform-specific NVIDIA GPU drivers to a container image( Ai era, everyone and their neighbor is running kubernetes GPU clusters). Without platform info in the referrer artifact, tools must download and inspect all driver variants to find a compatible one. By adding --artifact-platform to oras attach, tools can immediately identify and fetch only the platform-appropriate driver
suppose if we not , then download all driver artifacts ,examine their contents to determine compatibility ,select the appropriate one for the target platform and so on.

what you folks think?
