• Deprecated with no replacement in iOS 16.4.

Depends on: firebase/firebase-ios-sdk#11144

Currently FirebaseSessions is the only user of this API.

TODO

• Run tests
• Submit Remove references to deprecated CTCarrier for Sessions firebase/firebase-ios-sdk#11144
• Wait until the next major GoogleUtilities release

I believe this change needs to wait until the next GoogleUtilities major release to avoid breaking existing installs depending on GoogleUtilities 7.x

Hi @samedson, I changed the base branch to merge into release-8.0 as we are now working on prepping for GUls v8. Is this PR ready for a final review?

[samedson]
