AMD HIP Ray Tracing

[Stefan]

HIP RT is a ray tracing library for HIP, making it easy to write ray-tracing applications in HIP. The APIs and library are designed to be minimal, lower level, and simple to use and integrate into any existing HIP applications.
Although there are other ray tracing APIs which introduce many new things, we designed HIP RT in a slightly different way so you do not need to learn many new kernel types.
