Stefan Werner 02b5e27f89 Cycles: Add Intel GPU support for OpenImageDenoise
OpenImageDenoise V2 comes with GPU support for various backends. This adds a new class, OIDNDenoiserGPU, in order to add this functionality into the existing Cycles post processing pipeline without having to change it much. OptiX and OIDN CPU denoising remain as they are. Rendering on a supported Intel GPU will automatically select the GPU denoiser.

Device support is initially limited to the oneAPI devices that are supported by Cycles, but can be extended.

Ref #115045
