package/opencl-icd-loader: new package

This adds the OpenCL installable client driver (ICD) loader
which provides the 'libOpenCL.so' shared library needed to
run OpenCL programs.

Mesa3D can offer opencl implementations (such as rusticl),
but it does not provide 'libOpenCL.so'.

Without it, programs like 'clinfo' fail to build not
finding 'libOpenCL.so'.
