feat(llvm-test): upload riscv.json to github

[AFOliveira]

riscv.json is llvm-tablegen for risc-v.
Uploading it to github actions, allows users to download it, instead of building it locally.

Do we provide a link to this file somewhere?

Yes, it is embedded in the action. From what I could grasp, this is standard for the upload and did not document this part.

I'm confused. Are we expecting users to download this file from the action artifacts?

It's not about expecting users to download it. This artifact is generated by compiling LLVM, which is a time-consuming process and requires a reasonably capable machine. It's mainly useful for those who want to compare against LLVM locally or fix errors that appear in the CI (like in my case). Downloading it from the action artifacts is just a convenience for UDB developers to avoid the need to build LLVM locally. Therefore, it can be linked in other way, but I don't think it should have a static location, as it's not an output but rather a debugging aid for developers.
