Add CI run for HIP

[bernhardmgruber]

Currently, the CI only tests CPU targets and CUDA. We should extend it to also test compilation for AMD's HIP.

Compile tests can be performed in the current github runners. But to test runtime CUDA and HIP must be executed in our HZDR gitlab CI.

I am already totally fine with just compilation tests. I had a quick look into the ROCm docs and it seemed I would have to build their clang myself, so I bailed out. If you have a good resource for how to setup a HIP compilation environment, please link it here! Thx!

I suggest using the apt repositories. If you like to build ROCm you should use spack because AMD is maintaining spack better than their documentation on how to build ROCm.

For manual build I have only an outdated script: https://gist.github.com/psychocoderHPC/0f451dbbd79ee9a15dfaf3cb8298406e
