[FR]: Add privacy manifest to InAppMessaging&Sessions

[tetsu888]

Description

It appears that InAppMessaging & Sessions was missed when privacy manifests were added to the various modules in this repository.
I was expecting to see at least one entry for NSPrivacyAccessedAPICategoryUserDefaults.

FirebaseInAppMessaging:

FirebaseSessions:

firebase-ios-sdk/FirebaseSessions/Sources/Settings/SettingsCacheClient.swift

Line 51 in ed28962

private let cache: UserDefaults = .standard

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Similar to #12488, so far we've only published manifests for SDKs named by Apple on this list. We're still working on the Firebase SDKs that are not on that list.

To eliminate required reasons impact, all required reason symbols have been removed from Sessions (#12752) and InAppMessaging (#12757) (in addition to other SDKs like Performance). This will be released in the next Firebase release, 10.25.0.
