Fix T92308: OptiX denoising fails with high resolutions

The OptiX denoiser does have an upper limit as to how many pixels it can denoise at once, so
this changes the OptiX denoising process to use tiles for high resolution images.
The OptiX SDK does have an utility function for this purpose, so changes are minor, adjusting
the configured tile size and including enough overlap.
