Consider enabling Hermes JS engine for Android

[acostalima]

Issues

Hermes does not yet support Intl API. Therefore, we need to polyfill the runtime to be able to continue using react-intl. Is it possible to install a polyfill?

Performance gains

For JavaScript-based mobile applications, user experience benefits from attention to a few primary metrics:

• The time it takes for the app to become usable, called time to interact (TTI)
• The download size (on Android, APK size)
• Memory utilization
