Message:

Media: Introduce filters to customize the results from wp_get_loading_optimization_attributes().

This changeset introduces two filters that allow customizing the loading optimization attributes array returned from wp_get_loading_optimization_attributes() for individual HTML tags:

• The wp_get_loading_optimization_attributes filter can be used to modify the results from the WordPress core logic.
• The pre_wp_get_loading_optimization_attributes filter can be used to use entirely custom logic and effectively short-circuit the core function.

Props pereirinha, mukesh27, spacedmonkey, joemcgill.
Fixes #58893.
