Add required Privacy Manifest file for iOS

[muneer-khan]

Starting with Spring 2024 Apple requires third-party SDKs to add a Privacy Manifest file (similar to the privacy nutrition labels in the store). Apple specifically lists Capacitor as one of the SDKs that must include this manifest otherwise any App that includes it is not allowed to release an update (or new app) to the store.
