Add newly recommended method for RCTLinkingManager due to deprecation

Summary:
What existing problem does the pull request solve?

Beginning in iOS9, Apple has deprecated `-application:openURL:sourceApplication:annotations:`

`- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(nullable NSString *)sourceApplication annotation:(id)annotation NS_DEPRECATED_IOS(4_2, 9_0, "Please use application:openURL:options:") __TVOS_PROHIBITED;`

This PR uses the newly recommended method:

`- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey, id> *)`

while meanwhile, leaving the deprecated one for developers wishing to use the older `-application:openURL:sourceApplication:annotations:` for apps that support versions 8.x or less.

Benefits will include:
- [x] less warnings
- [x] official deprecation should happen when iOS 11 is deployed
- [x] TVOS support
Closes react/react-native#13615
