Wojciech Lewicki 97c7c6a4b6 fix: dispatch ContentSizeChange event on Fabric on iOS (#35816)
Summary:
On Fabric, `onContentSizeChange` of `TextInput` component was never fired on `iOS`, since the logic dispatching it was implemented in `RCTBaseTextInputShadowView` on Paper: https://github.com/facebook/react-native/blob/0f8dc067ac079f7b14696cfcafa37e3ec19a0409/Libraries/Text/TextInput/RCTBaseTextInputShadowView.m#L105. This class is not used on Fabric, therefore the event was never dispatched. On Paper, it was dispatched in `dirtyLayout` method,  so I added dispatching of this event based on the change of content size in `layoutSubviews` method, since this method seems the closest one on Fabric. I am not sure if it is the best place for it though.

Pull Request resolved: https://github.com/facebook/react-native/pull/35816

Test Plan:
Try to use `onContentSizeChange` callback in `TextInput` component:
```tsx
import React from 'react';
import {TextInput, SafeAreaView} from 'react-native';

const App = () => {
  return (
    <SafeAreaView style={{flex: 1, backgroundColor: 'red'}}>
      <TextInput
        multiline={true}
        placeholder="type here"
        onContentSizeChange={e => console.log(e)}
      />
    </SafeAreaView>
  );
};

export default App;

```
