When adding `decoding="async"` to images was introduced in <a href="https://core.trac.wordpress.org/changeset/53480">[53480]</a>, it did not provide the ability to customize that behavior specifically for image tags returned from `wp_get_attachment_image()`.

With this changeset it is now possible to explicitly provide a `decoding` value of e.g. boolean `false` in the `$attr` parameter of the function, to ensure the attribute is omitted.
