Using Dawn triggers a privacy-manifest problem with apple appstoreconnect submissions

[SoylentGraham]

Dawn uses abseil, which appears on apple's "privacy api using" list.
Dawn only uses string functions (Lost url to this citation), and abseil itself apparently is safe abseil/abseil-cpp#1604

To remedy this, the target that uses abseil (the emails from apple cite libwebgpu_dawn.dylib) we can add a PrivacyInfo.xcprivacy resource to our target (I'm using DawnNative as that's where I have my xcframework)

This generates a .bundle in my final .app output containing the privacy manfiest, which hopefully allows submission

[SoylentGraham]

Note; adding to the DawnNative target, means app now also need to include the DawnNative.lib generated by swift.
Maybe we can move the privacy to WebGpu target... have to see what apple approve

The above change hasn't worked - I think I need to turn that dylib into a framework and include it there
https://developer.apple.com/documentation/bundleresources/privacy_manifest_files/adding_a_privacy_manifest_to_your_app_or_third-party_sdk
Or possibly I can manually make a .bundle (as spm generates) and perhaps that will make it into the .xcframework
swift-webgpu_DawnNative.bundle.zip

Note to self, I have resolved this and the privacy meta, it can be injected into the framework as we build the xcframework - as I couldn't work out how to get it into the dawn cmake instructions when the .framework was built.
Which then means the xcframework needs to resign

Thanks for your investigation into this.

I have to admit, I have no experience of submitting to the app store (at least not in the last 10 years!), so I will probably need to update my knowledge on this!
