Message:

Media: Run the wp_content_img_tag filter once per image.

Prevent multiple identical img tags in a block of content causing the wp_content_img_tag filter to fire multiple times for that image.

Follow up to [53028].

Props superpoincare, flixos90, pbearne, peterwilsoncc.
Fixes #55510.
See #55347.
