Compositor: Added denoising node

This node is built on Intel's OpenImageDenoise library.
Other denoisers could be integrated, for example Lukas' Cycles denoiser.

Compositor: Made OpenImageDenoise optional, added CMake and build_env files to find OIDN

Compositor: Fixed some warnings in the denoising operator

build_environment: Updated OpenImageDenoise to 0.8.1

build_environment: Updated OpenImageDenoise in `make deps` for macOS
