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.

Summary:
Instead of using measure specs to set certain yoga properties on the root node (like max width, auto width, specific width), use yoga's calculateLayout(width, height) instead. The measure specs will be stored in the shadow node. This allows us to remove duplicated code that processes the measure specs and allows us to remove other logic like the enableLayoutCalculation() method.
This diff also removes MeasureSpecProvider. MeasureSpecProvider was originally introduced to pass previously measured view measure specs to the initial creation of the root shadow node, but it turns out that this is unnecessary. We can update the root layout specs from the root view instead.

I was trying to typeset mathematical equations in react native. When typesetting fractions, baseline of the fraction must be aligned with the baseline of others. The baseline of fraction will vary based on size of numerator and denominator.

In yoga, we can set custom baseline function using `YogaNode.setBaselineFunction` method. If this method is exposed in `ReactShadowNode` class, it will be easy to create custom native UI modules which requires setting custom baseline.

Summary:
This diff adds display:none support to React Native. This enables hiding components which still calling their render method and keeping them within the state of your application. This enables preserving state in a component even though the component is not visible. Previously this was often implemented by rendering a component off screen as a work around. See below playground for usage.
```
class Playground extends React.Component {
render() {
return (
<View style={{width: '100%', height: '100%', flexDirection: 'row', backgroundColor: 'white'}}>
<View style={{width: 100, height: 100, display: 'none', backgroundColor: 'red'}}/>
<View style={{width: 100, height: 100, backgroundColor: 'blue'}}/>
</View>
);
}

Summary:
This PR fixes#11096.
I don't know enough the ReactAndroid's source code so I don't know if this is correct but I hope it is.
In a recent commit (https://github.com/facebook/react-native/commit/d4b8ae7a8a3de314b5813e0bfcdf5fb265129d43), the `dispatchUpdates` method now returns a boolean to dispatch or not the `onLayout` event. This works well but if the content is unchanged, the line `nativeViewHierarchyOptimizer.handleUpdateLayout(this);` is never called. I don't know if it was intended but it was this which introduces my issue. I called this again even if the content didn't change. This was the behaviour before 0.38 so I guess I didn't break anything.
**Test plan (required)**
I tested my pretty big app with this fix and every screen is ok.
