[DevTools] Track virtual debug info from suspensey images (#34181)

Same as #34166 but for Suspensey images.

The trick here is to check the `SuspenseyImagesMode` since not all
versions of React and not all subtrees will have Suspensey images
enabled yet.

The other trick is to read back from `currentSrc` to get the image url
we actually resolved to in this case. Similar to how for Suspensey CSS
we check if the media query would've matched.
