This updates OIDN to 2.3.0-beta. The final version is planned to be
released in time for Blender 4.2 Beta. The most relevant changes:
1. Much higher quality when denoising with accurate prefiltering in *high*
quality mode, but at the cost of lower performance (use *balanced*
quality mode to revert to previous *high* quality mode)
2. Added new *fast* quality mode for 1.5-2x higher performance viewport
denoising
3. Lazy device module loading to avoid potential stability issues caused by
drivers of unused devices
4. Release CUDA primary context as soon as the OIDN device gets destroyed
to prevent potential memory leaks
To enable 2 and 3, code changes are needed in Blender, to be committed
separately.
