Make AccessibilityInfo.setAccessibilityFocus cross platform (#20229)

Summary:
Currently, `AccessibilityInfo.setAccessibilityFocus` is only available on iOS. The same behaviour can be achieved on Android by dispatching the proper accessibility event. I implemented the same function for Android, to make life slightly more convenient for the developer.

Today, developers must write something like this:
```
if (Platform.OS === 'ios') {
     AccessibilityInfo.setAccessibilityFocus(reactTag)
} else {
     UIManager.sendAccessibilityEvent(reactTag, 8)
}
```

With this change, the following is enough for both Android and iOS:
```
AccessibilityInfo.setAccessibilityFocus(reactTag)
```
