Docs: Correct the return type for wp_save_image_file().

Browse Source 
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].
