Site Health: Display a list of file formats supported by the GD library.

This adds the list of file formats supported by the GD library to the Media Handling section in Site Health.

This will help site owners debug any issues they encounter as support for newer, more modern image formats is added (such as WebP in [50810]).

Follow up to [50817].
