 In [changeset:"53480" 53480]:
 {{{
 #!CommitTicketReference repository="" revision="53480"
 Media: Add `decoding="async"` to image attributes.

 Dynamically add `decoding="async"` to image tags on the front end of a
 site to instruct browsers to download them in parallel.

 Modifies `wp_get_attachment_image()`, `get_avatar()` to include the
 attribute by default. Modifies `wp_filter_content_tags()` to add the
 attribute during the front-end render of the site.

 Introduces `wp_img_tag_add_decoding_attr()` to take an image tag and
 modify it to include the attribute. Introduces the filter
 `wp_img_tag_add_decoding_attr` used to define the default value for the
 attribute.
