IProtocolActivatedEventArgsWithCallerPackageFamilyNameAndData.Data is not marshaled in RedirectActivationToAsyncBug title

### Describe the bug

Because of the async nature of WinAppSDK redirection, via RedirectActivationToAsync, the OS launch logic assumes that it is safe to destroy the InputToken required by SharedStorageAccessManager.RedeemTokenForFileAsync, as soon as the secondary instance terminates. So it’s necessary to synchronize termination of the secondary instance with positive handoff of the redirect to the primary instance. That is, Instance 2 should wait until Instance 1 calls SharedStorageAccessManager.RedeemTokenForFileAsync. Today, that’s not happening – thus the bug.

Now ProtocolForResultsActivatedEventArgs implements IProtocolActivatedEventArgsWithCallerPackageFamilyNameAndData, which provides a mutable general purpose ValueSet (name-value pair collection) via the Data property:
[IProtocolActivatedEventArgsWithCallerPackageFamilyNameAndData.Data Property (Windows.ApplicationModel.Activation) - Windows UWP applications | Microsoft Learn](https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Flearn.microsoft.com%2Fen-us%2Fuwp%2Fapi%2Fwindows.applicationmodel.activation.iprotocolactivatedeventargswithcallerpackagefamilynameanddata.data%3Fview%3Dwinrt-22621&data=05%7C01%7Cdaferg%40microsoft.com%7C5731faca1f9947bce0a808db41051761%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C638175262359063639%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=OlAAelqyUyyPpIsY7EHpi94fp947VvzMcI%2BwVFQjSzE%3D&reserved=0)

So my original proposal to Yawen was to place all necessary redirection data in this store:
• The InputToken string required by SharedStorageAccessManager.RedeemTokenForFileAsync
• Any synchronization primitives (e.g., the name of an [EventWaitHandle](https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.albahari.com%2Fthreading%2Fpart2.aspx%23_CrossProcess_EventWaitHandle&data=05%7C01%7Cdaferg%40microsoft.com%7C5731faca1f9947bce0a808db41051761%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C638175262359063639%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=nrYoyCO3jEfUtn%2BXR3agWeOHXbfjRpj%2FTsqKvwaXbFA%3D&reserved=0))
• etc

But we struggled to get these mutations marshaled to Instance 1 – they were simply dropped, and we didn’t have time to debug into why. That strikes me as a bug, and fixing that should unblock your scenario.

### Additional context

_No response_

Start by reproducing the handoff through RedirectActivationToAsync and inspect how IProtocolActivatedEventArgsWithCallerPackageFamilyNameAndData.Data is transferred between instances. Verify whether the InputToken and synchronization data reach Instance 1; done means the mutations are preserved and the secondary instance waits for the primary instance to redeem the token.
