Chromium HTML attribute与c++接口对应关系分析

<a href="https://www.w3school.com.cn" target="_blank">访问 W3School</a>

前端这些属性定义在html_attribute_names.json5文件中：

third_party\blink\renderer\core\html\html_attribute_names.json5

html_attribute_names.json5会生成out\Debug\gen\third_party\blink\renderer\core\html_names.h

1、html_attribute_names.json5文件定义如下：
