Summary:
This diff formats the Java class files inside xplat/js/react-native-github. Since google-java-format was enabled in D16071401 we want to codemode the existing code so that users don't have to deal with formatter lint noise at diff-time.

Summary:
Potential breaking change: The signature of ReactShadowNode's onBeforeLayout method was changed
- Before: public void onBeforeLayout()
- After: public void onBeforeLayout(NativeViewHierarchyOptimizer nativeViewHierarchyOptimizer)
Implements same feature as this iOS PR: https://github.com/facebook/react-native/pull/7304
Previously, only Text and Image could be nested within Text. Now, any view can be nested within Text. One restriction of this feature is that developers must give inline views a width and a height via the style prop.
Previously, inline Images were supported via FrescoBasedReactTextInlineImageSpan. To get support for nesting views within Text, we create one special kind of span per inline view. This span is called TextInlineViewPlaceholderSpan. It is the same size as the inline view. Its job is just to occupy space -- it doesn't render any visual. After the text is rendered, we query the Android Layout object associated with the TextView to find out where it has positioned each TextInlineViewPlaceholderSpan. We then position the views to be at those locations.
One tricky aspect of the implementation is that the Text component needs to be able to render native children (the inline views) but the Android TextView cannot have children. This is solved by having the native parent of the ReactTextView also host the inline views. Implementation-wise, this was accomplished by extending the NativeViewHierarchyOptimizer to handle this case. The optimizer now handles these cases:
- Node is not in the native tree. An ancestor must host its children.
- Node is in the native tree and it can host its own children.
- (new) Node is in the native tree but it cannot host its own children. An ancestor must host both this node and its children.
I added the `onInlineViewLayout` event which is useful for writing tests for verifying that the inline views are positioned properly.
Limitation: Clipping
----------
If Text's height/width is small such that an inline view doesn't completely fit, the inline view may still be fully visible due to hoisting (the inline view isn't actually parented to the Text which has the limited size. It is parented to an ancestor which may have a different clipping rectangle.). Prior to this change, layout-only views had a similar limitation.
