Call setSurfaceProps when props change in SurfaceHandler (facebook#37087

)

Summary:
Pull Request resolved: facebook#37087

changelog: [internal]

Surface props can change during life cycle of a surface. This was supported before the new renderer as well. AppRegistry has a corresponding method for this: `AppRegistry.setSurfaceProps`.
To add support for this, we just need to call into `UIManager::setSurfaceProps`.
