Summary: This patch adds two pieces of functionality:
- Exposes `JSBundleLoader` to allow a developer to load JavaScript bundles as they choose.
- Adds `ReactBridge.loadScripFromFile` method which loads a JavaScript bundle from an arbitrary file path.
Example usage:
```
JSBundleLoader jsBundleLoader = new JSBundleLoader() {
Override
public void loadScript(ReactBridge reactBridge) {
reactBridge.loadScriptFromFile("/sdcard/Download/index.android.bundle");
}
};
mReactInstanceManager = ReactInstanceManager.builder()
.setApplication(getApplication())
.setJSBundleLoader(jsBundleLoader)
.setJSMainModuleName("") /* necessary due to TODO(6803830) */
.addPackage(new MainReactPackage())
.setInitialLifecycleState(LifecycleState.RESUMED)
.build();
```
