Summary: FlatList and VirtualizedList were typing this value as any instead of using the actual type from ScrollView. I started with that change and then fixed the type to solve the other callsites in the codebase.

Summary:
`<VirtualizedList />` will throw an error if the `renderItem` Prop component uses hooks. Function components without hooks and class components work without issue.
Super contrived Example

function FlatListItem({ item }) {
React.useEffect(() => console.log(item),[])
return (<Text>{item}</Text>);
}
<FlatList data={[1, 2, 3]} renderItem={FlatListItem} />
```
Example Error:
```

Summary:
This is the next step in moving RN towards standard path-based requires. All the requires in `Libraries` have been rewritten to use relative requires with a few exceptions, namely, `vendor` and `Renderer/oss` since those need to be changed upstream. This commit uses relative requires instead of `react-native/...` so that if Facebook were to stop syncing out certain folders and therefore remove code from the react-native package, internal code at Facebook would not need to change.
See the umbrella issue at https://github.com/facebook/react-native/issues/24316 for more detail.

Summary:
It's easy to accidentally trigger this invariant when adding / moving around a component that relies on a FlatList.
There might be some unexpected behavior when this occurs, i.e. messed up virtualization / viewability logging. But to me, that is a better outcome than crashing the JS context.

Summary:
Makes sure `onViewableItemsChanged` fires ASAP when `waitForInterations` is false.
This also works around another deeper bug where updates scheduled with `InteractionManager` aren't firing at all in some cases, and thus instead of just firing late, `onViewableItemsChanged` isn't firing until scroll which is not what we want with `waitForInterations: false`. That bug will require more digging.

Summary:
It seems (I used git history to confirm) that FlatList/VirtualizedList have ([since the begining](https://github.com/facebook/react-native/blame/c13f5d48cfe3e7c0f6c6d0b745b50a089d6993ef/Libraries/Lists/VirtualizedList.js#L79)) a `disableVirtualization` prop.
SectionList ([since it's begining](https://github.com/facebook/react-native/blame/abe737fe746406533798f9670e8e243cb18d5634/Libraries/Lists/VirtualizedSectionList.js#L98)) have a `enableVirtualization` prop, but since SectionList is VirtualizedSectionList which use VirtualizedList, this prop probably never did something. This fix just rename the prop properly so it can have an effect on the underlying VirtualizedList when you use a SectionList.
Since props are spread it's kind of working already, but the flow annotation are wrong (so it tells you it won't work/ you can't use it) which sucks.
(NB: I am doing this since I was trying to use a SectionList with react-native-web & server side rendering to get the all list, you can laugh).

Summary:
We ran into a problem trying to style the optional prop `ListHeaderComponent` in the `FlatList` library component. Essentially we wanted to make `ListHeaderComponent` a flex item that filled all of the empty space in the list if there was any. Unfortunately the `ListHeaderComponent` is later wrapped in a `View` that blocked our styling. The `View` component was necessary as it added styling to handle inverting the `FlatList`. Similarly `ListFooterComponent` was handled the same way.
We came up the simple solution of adding two new optional props, `ListHeaderComponentStyle` and `ListFooterComponentStyle`, that are of type `ViewStyleProp` that allow users to pass in styling for `ListHeaderComponent` and `ListFooterComponent`.
With this change we were able to do something like the following to get the header component to fill all empty space in the `FlatList`.
```
<FlatList
...
contentContainerStyle={{flexGrow: 1}}
ListHeaderComponent={<View style={{flex: 1}} />}
ListHeaderComponentStyle={{flexGrow: 1}}
...
/>
```
This solution will give users a lot more freedom when working with headers and footers.

I need `onViewableItemsChanged` to account for the length of any ListHeaderComponents
I couldn't find any tests that currently cover the use-case of a VirtualizedList + ListComponent + scroll with onViewableItemsChanged, so I have not added any tests - all previous tests pass however.

Summary:
VirtualizedList sets high priority rendering when scrolled to the top of a list even if the bottom of the rendered list is still far away and there's nothing further to render above. This causes severe non-responsiveness while dozens of items are waiting to be rendered and user inputs can't get through.
The fix is simply to not consider it high priority to render more items when we reach the top and the first item has already been rendered, or when we reach the bottom and the last item has been rendered.
The code change just splits the two cases (hitting the top and bottom) instead of combining them into one.
I wrote a small application that switches between two FlatLists.
Demo of the original VirtualizedList
<img src="https://user-images.githubusercontent.com/3090032/39456709-2c87069e-4d1b-11e8-8535-5bda6d59400c.gif" width="270" height="480">
I'm clicking pretty often on the button, but you can see that it only switches lists a split second after the rendering is all done because the javascript thread was being blocked.
Demo of the fixed VirtualizedList

You can see this one is significantly more responsive than the previous one.
