iGPU: Add compute engine offload capability

Add the intel-compute-runtime for opencl support.

```[ghaf@gui-vm:~]$ geekbench_x86_64 --gpu opencl```

`geekbench` is a large package, 477 MB, so it can be installed on demand
to the guivm by adding `pkgs.geekbench` to the
environment.systemPackages when required.

Create a new module for the ui specific test frameworks.
