 Docs: Correct the return type for `wp_save_image_file()`.

 Since WordPress 3.5, `wp_save_image_file()` uses `WP_Image_Editor` classes
 under the hood to save the images.

 While the `save()` method in those instances returns `array|WP_Error` and
 is documented as such, the return type of the `wp_save_image_file()`
 function was still left as `bool`.

 A better solution would be to adjust the function to return the documented
 boolean type. However, doing that after 20+ major WP releases would be a
 backward compatibility break, so the documentation is now updated instead.

 Includes:
 * Documenting the returned array using hash notation.
 * Adding a `@since` note for the `$image` parameter expecting a
 `WP_Image_Editor` instance.
 * Adding a `@since` note for the `$filesize` value being included in the
 returned array.

 Follow-up to [22094], [22619], [52837].
