Update PkgCI test_amd to use MI300x conductor cluster

[yamiyysu]

We want to migrate the workflows use MI300 and do not require cache support to migrate to our conductor cluster. A new runner with one GPU has been created

• label: linux-mi300-gpu-1
• namespace: arc-iree-gpu-1
• gitconfig url: https://github.com/iree-org/iree

This PR is to update the run label.

What drivers and software are installed on these new runners? Should we run under Docker (either in the runners themselves or in the job)?

Yeah discussing with Jodie offline. We can use the rocm gh runner docker for the runner instantiation, but I think it is probably best to specify the docker in the job (workflow file), so it is visible to everyone what rocm is being used

[ScottTodd]

I think it may depend on how long it takes to download and start the docker image. If it takes 5 minutes to download a 70GB docker image, configuring that in the runner itself could help hide some latency from workflows?

We could revive these dockerfiles as needed:

• https://github.com/iree-org/base-docker-images/blob/main/dockerfiles/amdgpu_ubuntu_jammy_x86_64.Dockerfile
• https://github.com/iree-org/base-docker-images/blob/main/dockerfiles/amdgpu_ubuntu_jammy_ghr_x86_64.Dockerfile

If we need to use Docker, I'd definitely prefer to use either upstream public images if no extra deps are needed or those iree-org ones.

[saienduri]

Yeah I was thinking about just using the latest released: rocm/dev-ubuntu-22.04:6.3. This one shouldn't be too bad to pull down I think. We can give it a shot and see how long it takes

[ScottTodd]

That would be great. These jobs do need CMake and ninja but otherwise the deps are pretty minimal.

[yamiyysu]

Agreed that it's clearer to set a container image in the workflow, but I'm not sure about the image download time. Updated and let's see how long it takes.
