RNGP - Move generateAutolinkingPackageList to core autolinking
Summary: This diff is part of RFC0759 react-native-community/discussions-and-proposals#759 Here I'm moving over the task to generate the Package List for Autolinking inside RNGP. The logic is the same as this one: https://github.com/react-native-community/cli/blob/73f880c3d87cdde81204364289f2f488a473c52b/packages/cli-platform-android/native_modules.gradle#L217 The class is generated as PackageList2 to avoid a duplicate class build failure with the current Autolinking from CLI. Changelog: [Internal] [Changed] - RNGP - Move generateAutolinkingPackageList to core autolinking Reviewed By: cipolleschi Differential Revision: D56637394 fbshipit-source-id: 929b42af3a0e1951cb7a0f4ace47bbbb84000780
