Adam Comella e40d1a1065 iOS: Introduce API for moving screen reader's focus
Summary:
This change introduces an API, `setAccessibilityFocus`, which moves the screen reader's focus to the passed in element. This causes VoiceOver to announce the element and draw a focus rectangle around it.

Similar functionality is already available in RN Android through the `sendAccessibilityEvent` method. Here's an example of what exists today in RN Android:

```
RCTUIManager.sendAccessibilityEvent(
  node,
  8 /* TYPE_VIEW_FOCUSED */);
```

Called `setAccessibilityFocus` on a couple of elements to verify that focus does indeed move when VoiceOver is enabled. Additionally, my team is using this change in our app.

Adam Comella 04790f1a78 Finish AccessibilityInfo implementation
Summary:
This PR is based on files ericvicenti gave me. Specifically, he gave me:
  - AccessibilityInfo.android.js
  - AccessibilityInfo.ios.js
  - AccessibilityInfoModule.java

Before this change, only a native iOS implementation of AccessibilityInfo existed. This change includes:
  - A native Android implementation of AccessibilityInfo.
  - JavaScript wrappers for the AccessibilityInfo module for both iOS and Android.
  - UIExplorer changes to illustrate how to use AccessibilityInfo on iOS and Android.
  - Documentation for the AccessibilityInfo APIs.

**Test plan (required)**

Tested the UIExplorer AccessibilityInfo example on iOS and Android with the screen reader both enabled and disabled.
