Peter Wilson 270259115c 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.
