Add appProperty to ReactRootView

Browse Source 
Summary:
To get on par with iOS this PR adds an `appProperty` to the `ReactRootView`. The documentation on the iOS side is here: [https://facebook.github.io/react-native/docs/communication-ios.html#properties.](https://facebook.github.io/react-native/docs/communication-ios.html#properties.)

You can pass in initial props with the `startReactApplication` method:
```java
…
Bundle initialProps = new Bundle();

bundle.putString(“initialKey”, “initialValue”);
mReactRootView.startReactApplication(mReactInstanceManager, "HelloWorld", initialProps);
setContentView(mReactRootView);
…
```

And later on properties can be updated this way:
```java
…
// Update props
Bundle updatedProps = mReactRootView.getAppProperties();

updatedProps.putString(“someOtherKey”, “someOtherValue”);

mReactRootView.setAppProperties(updatedProps);

// Replace props
Bundle newProps = new Bundle();

newProps.putString(“someKey”, “someValue”);

mReactRootView.setAppProperties(newProps);
…
Closes https://github.com/facebook/react-native/pull/13430
