 In [changeset:"56690" 56690]:
 {{{
 #!CommitTicketReference repository="" revision="56690"
 Media: Rely on `wp_get_loading_optimization_attributes()` to add
 `decoding="async"` to images.

 The `wp_get_loading_optimization_attributes()` function was introduced in
 6.3, as a single centralized place to control loading optimization
 attributes for various tags, most importantly images.

 This changeset consolidates the `decoding="async"` optimization, which was
 added in 6.1, to occur solely as part of
 `wp_get_loading_optimization_attributes()`, removing duplicate code and
 allowing centralized filtering based on [56651].

 As part of the change, the `wp_img_tag_add_decoding_attr()` function has
 been deprecated. The filter of the same name continues to be maintained
 for backward compatibility, as before covering only images that are part
 of a content blob such as post content (`the_content`).

 Props pereirinha, mukesh27, joemcgill, flixos90.
 Fixes #58892.
 See #53232.
