 Follow up from #53653.

 Looking at https://developers.google.com/speed/webp/docs/riff_container,
 the "extended" WebP file format `VP8X` may include a lossy or lossless
 "bitstream" chunk (`VP8 ` or `VP8L`) and few optional chunks: `ALPH`,
 `EXIF`, `ICCP`, `ANIM`, etc.

 Ideally the `wp_get_webp_info()` function should be extended to detect
 these features.
