Message:

Media: Generate WebP only for certain registered image sizes.

The existing filter image_editor_output_format receives an additional parameter $size_name which is populated whenever it controls the output format for a specific registered image size to create. Otherwise, it remains empty. In order to achieve this, a low level change has been added in bringing a new $size_name class property to the WP_Image_Editor base class, which is introduced in a backward compatible way that will not cause conflicts with custom implementations.

This parameter is then used in new logic inside the wp_default_image_output_mapping() callback function for the filter, controlling whether image/jpeg should map to image/webp output or not. By default, this is enabled for all WordPress core image sizes by default, and this list can be modified using a new wp_image_sizes_with_additional_mime_type_support filter, e.g. to remove core sizes or add custom sizes.

The customization per image size may be further enhanced by providing a more declarative API via a new parameter on the add_image_size() function.

Fixes #56526.
