Message:

Media: Generate animated image sub-sizes by default.

Fix an issue where sub-sizes of animated image uploads were static first-frame images, as GD and Imagick flatten animated images when resizing. When client-side media processing is active, generated images now retain animations.

Add a wp_generate_animated_image_subsizes filter (boolean, default true) so the client pipeline can keep or drop the animation in sub-sizes. The client-side consumption ships via the Gutenberg package updates in ​https://github.com/WordPress/gutenberg/pull/80385.

Fixes #65656, #28474.
