* Add AVIF, HEIF and HEIC partial support * Add them as media types. * Support reading metadata (Width, Height, Exif, etc.) from these formats. * Add a new template function IsImageResourceMeta to check if a resource supports image metadata operations, which will return true for AVIF, HEIF and HEIC resources even if they don't support full image operations yet. Fixes #14549
