Nested View and Text vertical alignment issue.

Description

Nesting View inside Text adds lineHeight's marginBottom to View and when we add Text inside that View it doesn't gets aligned properly.

Steps To Reproduce

1. Setup a CRNA or Expo app.
2. Replace the code in App.js with -

import { StatusBar } from "expo-status-bar";
import React from "react";
import { StyleSheet, Text, View } from "react-native";

export default function App() {
  return (
    <View style={styles.container}>
      <Text style={styles.outsideText}>
        Outside Text{" "}
        <View style={styles.insideView}>
          <Text>Inside Text</Text>
        </View>
      </Text>
      <StatusBar style="auto" />
    </View>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: "#fff",
    alignItems: "center",
    justifyContent: "center",
  },
  outsideText: {
    backgroundColor: "#cecece",
  },
  insideView: {
    backgroundColor: "#fcc9",
  },
});

3. Start your App on iOS or Android with yarn ios or yarn android.

Expected Results

The text should be in the same line aligned vertically. Like it looks when we run this example on the Web.

Snack, code example, screenshot, or link to a repository:

使用链接的 Snack 或 CRNA/Expo 应用并运行 yarn ios 或 yarn android，复现 issue 中 App.js 示例的对齐问题。跟踪 Text 内嵌套的 View 如何在 iOS 和 Android 上处理 lineHeight 和垂直布局。当嵌套的 Inside Text 出现在同一行，并且与 Outside Text 垂直对齐时，即表示完成。
