We need to migrate from deprecated react-native-fabric to react-native-firebase.
This PR enables following Firebase features:
* Analytics
* Crashlytics
* Performance

It also tracks screen view without the necessity of HOC.

Future work:
I won't do it in this PR because it's large enough, but we need to log more app events, like 'sent_message', 'open_admin', 'media_upload', etc.

On Room Actions, we have Files, Mentions, Starred and Pinned.
They have similar APIs and logic.
All of those could be merged into one generic view (MessagesView).
Maybe even Search could be in this merge.

Note: They're similar, but have own rules (unstar, unpin, etc).

This change may reduce 1MB to our release bundle size, since we're going to remove a lot of boilerplate.
