Reduce the amount of C++ code in user space for RN-Tester
Summary: This diff reduces the amount of C++ code in user space by: - Moving all the C++ implementation of the .defaults package inside a `react_newarchdefaults` shared library - Exposing only the entrypoint logic inside the RN-Tester's `OnLoad.cpp` file. Changelog: [Android] [Changed] - Reduce the amount of C++ code in user space for New Architecture Reviewed By: cipolleschi Differential Revision: D39381820 fbshipit-source-id: 9c4b5596b67b5a7ee58824319c80e325348ed06c
