NOTE that this gold is not fully correct itself. It has following
issues:
- indirect channel is incorrect
- missing indirect diffuse
- missing specular fresnel
See https://github.com/w23/xash3d-fwgs/issues/759
Committing it as a new gold for the sole reason of detecting changes
compared to current vulkan branch state. More correct gold will be
submitted when the issues above are fixed.
Also, changes rendertest script to use the new denoiser, and remove some
extra text messages things from the frame.
