RNGP - Automatically Configure Dependencies for ReactNative & Hermes

Summary:
This is part of a series of tasks to make the React Native Gradle Plugin (RNGP) variant-aware.

I'm extending RNGP to do autoconfiguration of dependencies for React Native and Hermes Engine using the Utils classes which were introduced before.

Changelog:
