TextInput onContentSizeChange returns incorrect layout size instead of content size on Android

Description

The onContentSizeChange prop of the TextInput component does not work on Android as it does on iOS. On Android it seems to be returning the layout height and width of the TextInput view, rather than the height and width of the text.

This same issue has been reported before in https://github.com/facebook/react-native/issues/25487 and https://github.com/facebook/react-native/issues/19696, but does not seem to have been fixed

Steps To Reproduce

Run the following code on both iOS and Android platforms, note the inconsistency in the logged values from `contentSize:

import React from 'react';

import { View, TextInput } from 'react-native';

export default class App extends React.Component {
  render() {
    return (
      <View style={{ flex: 1, marginTop: 40 }}>
        <TextInput
          defaultValue="test"
          onLayout={ e=> {
            console.warn("single line layout", e.nativeEvent.layout)
          }}
          style={{ width: 200, lineHeight: 30, backgroundColor: '#CCC' }}
          onContentSizeChange={ e=> {
            console.warn(e.nativeEvent.contentSize)
          }}
        />
        <TextInput
          defaultValue="test"
          onLayout={ e=> {
            console.warn(e.nativeEvent.layout)
          }}
          multiline
          style={{ width: 200, lineHeight: 30, backgroundColor: '#CCC' }}
          onContentSizeChange={ e=> {
            console.warn(e.nativeEvent.contentSize)
          }}
        />
      </View>
    )
  }
}

Expected Results

On iOS as you edit text on single or multiline TextInput you get the actual width of the characters entered. I would expect the same behavior on Android. Effectively this functionality is not actually implemented on Android at the moment.

See code sample in reproducible steps

Start with the TextInput component's Android handling of onContentSizeChange and reproduce the provided single-line and multiline example, comparing contentSize with onLayout on both platforms. Done means Android reports the text dimensions consistently with iOS for both cases; the issue names no specific file or test.
