This also replaces the Use Alpha setting. We now have these alpha modes: * Straight: store RGB and alpha channels separately with alpha acting as a mask, also known as unassociated alpha. * Premultiplied: transparent RGB pixels are multiplied by the alpha channel. The natural format for renders. * Channel Packed: different images are packed in the RGB and alpha channels, and they should not influence each other. Channel packing is commonly used by game engines to save memory. * None: ignore alpha channel from the file and make image fully opaque. Cycles OSL does not correctly support Channel Packed and None yet, we are missing fine control over the OpenImageIO texture cache to do that. Fixes T53672
