Cycles: add Optix device backend
This uses hardware-accelerated raytracing on NVIDIA RTX graphics cards.
It is still currently experimental. Most features are supported, but a few
are still missing like baking, branched path tracing and using CPU memory.

For building with Optix support, the Optix SDK must be installed. See here for
build instructions:
