Title: Add `.currentSrc` property to the `<img>` IDL

It's probably useful to know what URL was chosen by the algorithm. More information is potentially useful, but URL is the minimum viable piece of info - using it, you can reliably tell what `` was chosen, what the type is, etc (assuming people don't repeat urls, which there's no reason to do).
