rn: add Firebase integration

This is done at the app level, not the SDK.

Currently 2 Firebase services are used:

  - Crashlytics
  - Dynamic Links

They are enabled in tandem, if the appropriate Google services file
(GoogleService-Info.plist on iOS or google-services.json on Android) is found.

Each service needs to be individually enabled in the Firebase console.

android/app/build.gradle

 apply plugin: 'com.android.application'
 
+boolean googleServicesEnabled = project.file('google-services.json').exists()
+
+// Crashlytics integration is done as part of Firebase now, so it gets
+// automagically activated with google-services.json
+if (googleServicesEnabled) {
+    apply plugin: 'io.fabric'
