openvkl: add recipe for Intel Open Volume Kernel Library

Intel(R) Open Volume Kernel Library (Intel(R) Open VKL) is a collection of
high-performance volume computation kernels, developed at Intel. The
target users of Open VKL are graphics application engineers who want to
improve the performance of their volume rendering applications by
leveraging Open VKL’s performance-optimized kernels, which include
volume traversal and sampling functionality for a variety of volumetric
data formats. The kernels are optimized for the latest Intel(R) processors
with support for SSE, AVX, AVX2, and AVX-512 instructions.

Open VKL provides a C API, and also supports applications written with
the Intel(R) Implicit SPMD Program Compiler (Intel(R) ISPC) by also
providing an ISPC interface to the core volume algorithms. This makes it
possible to write a renderer in ISPC that automatically vectorizes and
leverages SSE, AVX, AVX2, and AVX-512 instructions. ISPC also supports
runtime code selection, thus ISPC will select the best code path for
your application.
