[FR]: Make Firebase Screen ID Parameter Editable

[sevatt1995]

1. I want to be able to identify unique screens via a guid field in order to track the performance of a screen over time irrespective of the content displayed on that screen in such a way that I can track what screen a user was previously on based on the same field. This will enable me to use firebaseScreenName to log the page title and enables between cross domain tracking between web and app using GA4s default reporting fields
2. Firebase currently sets screen ids based on the app instance id, meaning that Screen A will have a different firebaseScreenId for user B and C and if user B deletes and then reinstalls the application
3. Make firebaseScreenId an edible/overridable parameter like firebaseScreenName and firebaseScreenClass

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
