Add AVIF, HEIF and HEIC partial support (only metadata for now)

* 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.
