Reopening discussion from: #7369

Apple released a new framework for iOS 14.3+, aimed to attribute app-download campaigns that originate from the App Store, Apple News, or Stocks on iOS devices.

From my understanding, this new framework that will be replacing the iAd framework. I'm wondering if the Firebase SDK will be adopting it with firebase_campaign and conversion event attribution integrated just like iAd.
