Introduce OIDNDenoiserBase composition helper to eliminate code duplication between CPU and GPU OIDN implementations: - Move shared device, filter, and quality management to base class - Consolidate custom weights loading and common filter parameter setup - Both CPU and GPU denoisers access OIDN state through base_ member - Lazy device initialization moved to denoise_create_if_needed() - Filter lifecycle unified across both implementations Pull Request: https://projects.blender.org/blender/blender/pulls/152637
