Cycles: Improve OptiX denoising with dark images and fix crash when denoiser is destroyed

Adds a pass before denoising that calculates the intensity of the image, which can be
passed into the OptiX denoiser for more optimal results for very dark or very bright images.

In addition this also fixes a crash that sometimes occurred on exit. The OptiX denoiser object
has to be destroyed before the OptiX device context object (since it references that). But in
C++ the destructor function of a class is called before its fields are destructed, so
"~OptiXDevice" was always called before "OptiXDevice::~Denoiser" and therefore
"optixDeviceContextDestroy" was called before "optixDenoiserDestroy", hence the crash.
