Enhance Flow types for RefreshControl specifying `onRefresh` props type.
There are still 2 `any` left using `requireNativeComponent` that need to be addressed to turn Flow to strict mode.
I went through `RCTRefreshControl` and `AndroidSwipeRefreshLayout` classes to understand where this method came from.

Summary:
This PR increases the speed at which cached images are loaded and displayed on the screen. Images are currently cached in memory using RCTImageCache, but each time they are loaded, a round trip through RCTNetworking happens before RCTImageCache is even checked. This is likely so that RCTNetworking can handle the caching behavior required by the HTTP headers. However, this means that at the very least, images are read from disk each time they're loaded.
This PR makes RCTImageLoader check RCTImageCache _before_ sending a request to RCTNetworking. RCTImageCache stores a bit of information about the response headers so that it can respect Cache-Control fields without needing a roundtrip through RCTNetworking.
Here are a couple of graphs showing improved loading times before this change (blue) and after (red) with SDWebImage (yellow) as a baseline comparison. The increase is most evident when loading especially large (hi-res photo size) images, or loading multiple images at a time.

More performance gains can potentially be had by increasing the size limit of RCTImageCache: 1a6666a116/Libraries/Image/RCTImageCache.m (L39) but this comes at the tradeoff of being more likely to run into OOM crashes.

Summary:
Changing the the this.props.visible if to be ` if (!!this.props.visible === false)` . So passing undefined, or other values wont set the modal to be visible. Granting that anything that is not true, will set the modal to null on the render.
I make this this PR, because on the company that im working, we used a lot of RN. At the moment, we arent using anything like flow or TS. But to grant that the modals will only show if they are set visible to true i have changed the if made.

Summary:
If a view inside of an inline view became dirty (e.g. its top/left prop changed), its position would not update on screen. This is because Yoga didn't know the view needed to be relaid out because Yoga's dirty signal didn't propagate all the way up to the root.
The problem is that inline views don't have a parent in the Yoga tree causing Yoga's dirtiness signal propagation to get cut off early. The fix is, when an inline views gets dirty, mark the parent Text's Yoga node as dirty. This will cause Yoga's dirtiness signal to propagate all the way up to the root node.
Yoga has a hook to inform you when your node is marked as dirty: `YGNodeSetDirtiedFunc`. We leverage this to find out when an inline view's Yoga node gets dirtied.
React Native almost handled this case. Everything worked fine as long as the inline view was nested inside of a virtual text node like this:
```
<Text>
<Text>
<InlineView />
</Text>
</Text>
```
However, the bug repros when the inline view is nested in a non-virtual text node:
```
<Text>
<InlineView />
</Text>
```
The fix is to move the special dirtiness propagation logic from `RCTVirtualTextShadowView` to `RCTBaseTextShadowView`.
**Test Plan**
Created an inline view. Tested the following kinds of updates on the inline view's content:
- Moved the content
- Removed the content
- Added the content
Tested this for an inline view that is directly inside of a text node as well as one that is nested under a virtual text node.
Here's the code I used for the inline view that moved its content after 2 seconds:
```
const RN = require('react-native');
const React = require('react');
export default class InlineView extends React.Component {
constructor(props, context) {
super(props, context);
this.state = { posBottom: false };
}
componentDidMount() {
super.componentDidMount && super.componentDidMount();
setTimeout(() => { this.setState({ posBottom: true }); }, 2000);
}
render() {
const pos = this.state.posBottom ? 25 : 0;
const color = this.state.posBottom ? 'pink' : 'green';
return (
<RN.View style={{ width: 50, height: 50, backgroundColor: 'steelblue'}}>
<RN.View style={{ width: 25, height: 25, top: pos, left: pos, backgroundColor: color }} />
</RN.View>
);
}
}
```

Summary: Split up InitializeCore into a bunch of modules. The idea here is to make it easier for apps to just get the initialization logic they want and leave behind what they don't; for example, if you don't want the Map/Set polyfills, instead of requiring InitializeCore you can require the modules you want from it.
