Add ability to lazy load Native Java Modules

Browse Source 
Summary: Utilizes the build time annotation processor ReactModuleSpecProcessor that creates ReactModuleInfos for modules annotated with ReactModule and listed in the ReactModuleList annotation of LazyReactPackages. This way we don't have to instantiate the native modules to get the name, canOverrideExistingModule, and supportsWebWorkers values of the native modules. In the NativeModuleRegistry, we either store these ReactModuleInfos inside of a ModuleHolder or if we can't get the ReactModuleInfo for a specific module we instantiate that module to get the values (as we previously did) to store in a LegacyModuleInfo.
