Inspired by D12936 and D12929, this patch adds general purpose "Combine Color" and "Separate Color" nodes to Geometry, Compositor, Shader and Texture nodes. - Within Geometry Nodes, it replaces the existing "Combine RGB" and "Separate RGB" nodes. - Within Compositor Nodes, it replaces the existing "Combine RGBA/HSVA/YCbCrA/YUVA" and "Separate RGBA/HSVA/YCbCrA/YUVA" nodes. - Within Texture Nodes, it replaces the existing "Combine RGBA" and "Separate RGBA" nodes. - Within Shader Nodes, it replaces the existing "Combine RGB/HSV" and "Separate RGB/HSV" nodes. Python addons have not been updated to the new nodes yet. **New shader code** In node_color.h, color.h and gpu_shader_material_color_util.glsl, missing methods hsl_to_rgb and rgb_to_hsl are added by directly converting existing C code. They always produce the same result. **Old code** As requested by T96219, old nodes still exist but are not displayed in the add menu. This means Python scripts can still create them as usual. Otherwise, versioning replaces the old nodes with the new nodes when opening .blend files. Differential Revision: https://developer.blender.org/D14034
