ci : re-enable rocm build on amd64 (#18439)

This was disabled in #9340 due to compiler crash, but seems to build now as confirmed by the latest comments in #11913.

I've also managed to build the image with `docker build -f .devops/rocm.Dockerfile .` (for all three stages, `full`, `server` and `light`).

A quick attempt at trying to build an arm64 image failed. Since none of the other images are build for arm, I only enabled the amd64 one.

The `runs_on` option was added to match the other entries.
