Add a Privacy Manifest for iOS

[mpgxvii]

Apple recently introduced new privacy protocols for third-party SDKs, requiring SDK authors to declare approved reasons for API usage within their SDKs to enhance transparency and user privacy. This is required before we can release a new version.

ITMS-91061: Missing privacy manifest - Your app includes “Frameworks/Capacitor.framework/Capacitor”, which includes Capacitor, an SDK that was identified in the documentation as a privacy-impacting third-party SDK. Starting February 12, 2025, if a new app includes a privacy-impacting SDK, or an app update adds a new privacy-impacting SDK, the SDK must include a privacy manifest file.
