**Breaking Change Summary**
On Android, the following properties now return a different number:
- `Dimensions.get('window').fontScale`
- `Dimensions.get('screen').fontScale`
- `PixelRatio.getFontScale()`
This is a breaking change to anyone who was using these properties because the meaning of these properties has now changed.
These properties used to return a value representing font scale times density ([`DisplayMetrics.scaledDensity`](https://developer.android.com/reference/android/util/DisplayMetrics.html#scaledDensity)). Now they return a value representing just font scale ([`Configuration.fontScale`](https://developer.android.com/reference/android/content/res/Configuration.html#fontScale)).
**PR Description**
This PR changes a few things:
- Correctly exposes the font scale to JavaScript as `Dimensions.get('screen').fontScale`. UIManager was exporting `DisplayMetrics.scaledDensity` under the name `fontScale`. How

Summary:
The index is used to make sure the layout corresponds to the correct index, which can get
out of sync if cell layout is cached and then cells are re-ordered.

Summary:
Simple API takes structured `sections` prop instead of `data` array. `sections` is an array of
`Section` objects, each of which has a `key` and an `itemData` array which is analogous to a
`FlatList` `data` prop, plus optional props like `ItemComponent` that can be overridden on a
per-section level, allowing heterogeneous section item rendering via clean composition.
Flattens the sections data and renders with VirtualizedList under the hood. Doesn't support
sticky headers yet.

There's a few placeholders, one could be for a little graphic that to represent the node graph (would appreciate if someone with good design skills would make one for me hehe) and the other one for other resources about native Animated if you know of any other.

The goal of this PR is to enable the buck module `uimanager` to depend on `modules/core` without introducing any dependency cycles.
PR #11008 relies on this PR. PR #11008 needs `uimanager` to depend on `modules/core` so that `uimanager` can fire events using `RCTDeviceEventEmitter` which is in `modules/core`.
This PR moved a number of classes and interfaces:
- `com.facebook.react.modules.debug.DeveloperSettings` -> `com.facebook.react.modules.debug.interfaces.DeveloperSettings`
- `com.facebook.react.devsupport.DevOptionHandler` -> `com.facebook.react.devsupport.interfaces.DevOptionHandler `

Summary:
Fixes ```align-content:strech``` on nodes without specified cross dimension, if there are multiple lines. Currently it uses the full height of the parent, but it has to use the line height. As we don't know the number of lines until here, we need to realign the relevant children.

Summary:
Due to the changes in 46817a38. We have a bug if the layout changes.
This PR fixes this bug and adds a test for it.
Additionally it correctly marks negative percentage values as undefined dim.
It also changes the ```resolvedDimensions``` to use a reference instead of the full value in order to minimize the memory requirement of a ```YGNode``` and reduces the copying of the ```YGValue```.

Summary:
We should unmock React just because we do that elsewhere and tests work better
that way. I was trying to get React tests working in this repo but because
we do so many special things in the React Core repo I gave up.
These test run in the React Core repo already.

Summary:
Simple cleanup for AppRegistry.
Also added `registerSection()` helper to mark registered components as app-specific sections. Sections can be treated in many custom ways, e.g. they could just indicate the top level tabs, or something else. A bunch of helpers are also added.

Summary:
If we throw an exception from a UIOperation, the UI is likely in a bad state and we shouldn't execute any other operations on it. In non-dev mode, this would mean we've crashed and don't have to worry about that. But in dev mode, we may have shown a redbox and the instance is still active. This means doing something like reloading, which will trigger onPause and thus flush more UI operations, can crash the app while its sitting on a red box.
This diff aims to prevent that by no longer executing UI operations after one has thrown an exception.
