feat: add expo support for brownfield gradle plugin

[hurali97]

Summary

This PR adds support for Expo projects. The changes in this PR relates to embedding the Expo third party dependencies or libraries in the brownfield module AAR. Without this change, there will be a crash at the run-time when react-native tries to invoke ExpoModules which in turn look for its libraries like expo-image and if it will not be provided with the AAR then a crash will happen, since the classes won't be resolved.

We achieve this solution by evaluating the dependencies associated with expo project. What this means is that internally expo gradle plugin adds their third party dependencies using api and host these either in a local maven repo OR as a subproject. Since, expo project is linked in settings.gradle file it is available for the brownfield module.

Hence we evaluate the expo project and get its dependencies. Then we embed these dependencies for the brownfield module.

The above changes can be opted in by:

reactBrownfield {
    isExpo = true
}

Test plan

Tested these changes on both Expo and bare RN projects - 🟢
