DynamicLinkData class not initializable due to AbstractSafeParcelable->findCreator not finding the creator for the class.

Describe the bug

A while ago I created a pull request #2297 to improve / fix firebase dynamic link authentication. Back then I tried the login mechanism on my local version. Just now I tried to login in an app using the official microg release and encountered this exception:

So AbstractSafeParcelable.findCreator() is not finding the com.google.firebase.dynamiclinks.internal.DynamicLinkData$000Creator class, which, suggesting from the name could be some auto generated class.

@zainarbani I do see that you committed zainarbani@ce0802d in the pull request to change DynamicLinkData to extend from AbstractSafeParcelable instead of AutoSafeParcelable. Myself not familiar with these two Parcelable mechanisms, may it be possible that something is missing for the AbstractSafeParcelable to work?

To Reproduce

1. Open a dynamic "email login link" with the appropriate app, which is internally using firebase dynamic links
2. microg crashes

Expected behavior
Microg should not crash and pass the link data to the app

System
Android Version: 14
Custom ROM: LineageOS 21

Sorry @zainarbani, it was @marvin who refactored via 3ccb5f4
