[iOS] VoiceOver reads the placeholder in TextInput

Description

When setting a placeholder in the TextInput field, VoiceOver reads the placeholder text. This causes problems when an accessibilityLabel is also provided.

Expected behaviour: Placeholder should not be read by a screen reader as it is just a visual component.

Steps to reproduce

Try this sample code:

import React from 'react';
import {SafeAreaView, StyleSheet, TextInput} from 'react-native';

const TextInputExample = () => {
  const [text, onChangeText] = React.useState('');

  return (
    <SafeAreaView>
      <TextInput
      placeholder="text input"
      accessibilityLabel="text input"
        style={styles.input}
        onChangeText={onChangeText}
        value={text}
      />
    </SafeAreaView>
  );
};

const styles = StyleSheet.create({
  input: {
    height: 40,
    margin: 12,
    borderWidth: 1,
    padding: 10,
  },
});

export default TextInputExample;

从提供的 Snack reproducer 及其 TextInput 配置开始，然后追踪 React Native 中 iOS TextInput 的无障碍行为。当提供 accessibilityLabel 时 VoiceOver 不再读出 placeholder，同时所报告的 TextInput 行为保持不变，即视为完成。
