Privacy manifest aggregation picks reasons restricted to third-party SDKs

Description

#44214 implemented a privacy manifest agregation mechanism, which would iterate through the privacy manifests from dependencies and add their required API reasons to the app privacy manifest.

However, according to the Apple documentation on privacy manifests, there are reasons that should only be used by third-party SDKs, such as 0A2A.1 and C56D.1. These reasons should not be copied into the app privacy manifest since the app is not a third-party SDK. Instead, the app developer should check which of the other reasons on the respective category applies to their usage of the third-party library.

So the aggregation mechanism should check if the reasons used in the privacy manifests from the dependencies are third-party exclusives. If they are, they should not be added to the app privacy manifest, and the developer could be prompted to pick other reasons.

Steps to reproduce

1. Add a dependency whose privacy manifest declares a reason restricted to third-party SDKs, such as react-native-blob-util. That is already set up on the reproducer repo.
2. On the ios directory, run bundle install + bundle exec pod install
3. The PrivacyInfo.xcprivacy will be changed. It will have the 0A2A.1 reason on the NSPrivacyAccessedAPICategoryFileTimestamp, which is restricted to third-party SDKs

No response

Start by reading the privacy manifest aggregation implementation from #44214, then reproduce the issue in the linked rn-privacy-manifest-bug repository with bundle install and bundle exec pod install. Done means reasons restricted to third-party SDKs, such as 0A2A.1 and C56D.1, are not copied into the app's PrivacyInfo.xcprivacy, while other dependency reasons continue to aggregate correctly.
