Use the new API and secureCoding protocol

[Zelimir-Koljesar-ck]

Description

The reason I am reaching out is because we have an outside vendor that flagged certain lines of codes as a security issue when analyzing our 3rd party dependencies. In order to stay compliant we need to remedy this issue but we need support. https://github.com/firebase/firebase-ios-sdk/blob/b761b15097304b85d8ba3fec42b317498ef8b73a/FirebaseMessaging/Sources/Token/FIRMessagingTokenStore.m#L105 Would it be possible to upgrade the relevant code to use newer, secure APIs. The code in question is tagged with TODOs already, so the team should be aware of the need. We're trying to see if you can help us get this work prioritized and scheduled.
