Fix displaying hero images over blurry image placeholder (#32806)

* Fix displaying hero images over blurry image placeholder

This change allows us to immediately display SSR images when they load, even if this occurs before JS load (or JS fails to load). Before, these images would be stuck behind the blurry image placeholder due to the z-index stacking.

* Fix any placeholder inside SSR amp-img
