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.

- Refactored Message component to use React.memo and re-render only what's necessary
- Added a test mode to toggle markdown parse by long press drawer (it'll be removed in the next release)

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.
