Add w/a to missing script in intel-opencl-rt package from conda-forge (#2689)

There are missing `set-intel-ocl-icd-registry.ps1` and
`unset-intel-ocl-icd-registry.ps1` scripts when installing
`intel-opencl-rt` package from the conda-forge
([intel-compiler-repack-feedstock/#72](conda-forge/intel-compiler-repack-feedstock#72)).

This PR implements a temporary w/a until the issue is resolved. The w/a
assumes to force `intel-opencl-rt` installation from Intel channel.
