Add support for Build Variants to react.gradle
Summary: This PR adds support for Android Gradle [Build Variants](https://sites.google.com/a/android.com/tools/tech-docs/new-build-system/user-guide#TOC-Build-Variants) when generating the JS bundle. **Before**: only supported "bundleDebugJsAndAssets" and "bundleReleaseJsAndAssets" **Now**: all variants are supported Examples: "bundleDevDebugJsAndAssets", "bundleStageAlphaJsAndAssets", or "bundleBetaJsAndAssets" The Gradle script will automatically create bundle tasks for each build variant found in a project. Closes https://github.com/facebook/react-native/pull/4686 Reviewed By: svcscm Differential Revision: D2815856 Pulled By: foghina fb-gh-sync-id: 4518de70d178205bc3e5044d2446b56c40298da2
