Meta only. Attaches pixel measurement to the ad regardless of the optimization goal (the "Website events" tracking row in Ads Manager). pixelId becomes the ad's tracking_specs (offsite_conversion + fb_pixel); urlTags becomes the ad's url_tags (click-tracking query params). Applied on the legacy single-creative shape, every ad of the multi-creative shape, and the attach shape. NOTE: tracking lives on the AD object and is not inherited from the ad set, so pass it on EVERY attach call that should carry the pixel.
