Summary:
Currently, height is sometimes the only valid option for pushing `TextInput` up in the layout on Android. The problem is when switching keyboards. For instance, switching from ABC to emojis. This will trigger keyboard show events and recalculate the height for the `KeyboardAvoidingView`. Since the keyboard is still showing, the view has the height that was previously calculated and thus `frame` represents that. This means the `frame.height` has adjustments for the keyboard calculated in it, but it is used the same way as if the keyboard was not showing. This results in wrong calculation and the input showing at the incorrect place in the layout (mostly hidden under the keyboard)
This fix simply uses the previous calculation to offset `frame.height`, resulting in the correct height and smooth switching between keyboards. It's also scoped only to height mode since that's where the problem shows.
_Note: I mention android here, but it fixes it for both platforms. It's just that iOS usually works best with different behaviour so it's rarely used there._
## Changelog
[General] [Added] - Include `this.state.bottom` when calculating new keyboard height to fix android keyboard switching
Pull Request resolved: https://github.com/facebook/react-native/pull/34749
Test Plan:
With simple code:
```jsx
import { StatusBar } from "expo-status-bar";
import React from "react";
import {
KeyboardAvoidingView,
StyleSheet,
Text,
TextInput,
View,
} from "react-native";
export default function App() {
return (
<KeyboardAvoidingView style={styles.container} behavior="height">
<Text>Open up App.js to start working on your app!</Text>
<StatusBar style="auto" />
<TextInput style={{ backgroundColor: "red", width: "100%" }} />
</KeyboardAvoidingView>
);
}
const styles = StyleSheet.create({
container: {
padding: 32,
flex: 1,
backgroundColor: "#fff",
alignItems: "center",
justifyContent: "space-between",
},
});
```
Notice the consistency of the TextInput after the changes, while before it would just move around more you switch the keyboards.

Summary:
Fix `KeyboardAvoidingView` height on iOS when "Prefer Cross-Fade Transitions" is enabled by adding an additional check to `_relativeKeyboardHeight` verifying if `prefersCrossFadeTransitions()` is true and `keyboardFrame.screenY` is `0` and treating this special case. The issue was caused by the native RCTKeyboardObserver where the `endFrame` reported by `UIKeyboardWillChangeFrameNotification` returns `height = 0` when Prefer Cross-Fade Transitions" is enabled
and unfortunelly there isn't much we can do on the native side to fix it.

Summary:
ScrollView has special behavior when the keyboard is open, but starts listening to keyboard events on mount. This means a ScrollView mounted after the keyboard is already up (e.g. for a typeahead) is not initialized to the keyboard being up.
This change adds `Keyboard.isVisible()` and `Keyboard.metrics()` APIs to allow seeding initial keyboard metrics.

Summary:
Changelog: Fix possible race condition inside `KeyboardAvoidingView`
Fabric has different order of events
In Fabric, `keyboardWillChangeFrame` event is fired before `onLayout`, but in Paper it is the other way around.
`KeyboardAvoidingView` depends on the order of events to function properly. Inside `_relativeKeyboardHeight` 0 is returned if `this._frame` is null.
To fix this, `bottom` margin is recalculated whenever `keyboardWillChangeFrame` or `onLayout` is triggered.

Summary:
I'm using RNN, which embeds RN view inside native view controllers.
On iOS 13, a modal view controller is "floating" and is offset from the top of the screen.
This causes the calculation of inset in `KeyboardAvoidingView` incorrect as it mixes local view controller coordinate space, with keyboard's screen coordinate space.

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.

Summary:
when a hardware keyboard is connected, the virtual keyboard can be hidden (this can easily be demonstrated in the simulator), which means the height of the keyboard is 0. When in this case a `LayoutAnimation` is scheduled, the `KeyboardAvoidingView` won't be affected, but the next layout change will be animated, which can have unintended side-effects. This can also trigger the `Overriding previous layout animation with new one before the first began` warning.
<details>
<summary>Screenshot</summary>

</details>
Open the `KeyboardAvoidingView` example in the `RNTester` project, import `LayoutAnimation` and add something rendered conditionally to the content of the `Modal`, e.g.;
```jsx
{this.state.behavior === 'position' &&
<Text>We're using position now</Text>
}
```
Then update the `onSegmentChange` handler with a `LayoutAnimation`;
```js
onSegmentChange = (segment: String) => {
LayoutAnimation.easeInEaseOut();
this.setState({behavior: segment.toLowerCase()});
};
```
Now open the example in the simulator and play with the "Toggle Software Keyboard" option;

Now when you focus the input, no keyboard should appear, and when you then press an option of the segmented control, you should get the beforementioned warning.
After this change this warning will no longer appear, but the component still behaves the same as before.

* **Why make this breaking change**: These methods are not meant to be public. For example, the exposed `onLayout` function is not a prop that accepts a function like is typical of the rest of React Native but is the internal method that is called when the component's onLayout is triggered.

Summary:
The relevant changes in the PR are to Libraries/StyleSheet/EdgeInsetsPropType.js; the rest are just removals of FlowIgnores.
The definition of the relevant types is [here](https://github.com/facebook/flow/blob/master/lib/react.js#L262-L271).
The long and short of it is that for whatever reason, Flow is unable to realize that `ReactPropsChainableTypeChecker` is a subtype of `ReactPropsCheckType` unless we assert it. Once we explicitly hint this to the typechecker, it realizes that `EdgeInsetsPropType` is indeed a valid React PropType, and stops complaining that it isn't.
