feat: add a feature to import cookies from Chrome automatically.

[ginqi7]

Add a feature to import cookies from Chrome.

You can set eaf-browser-auto-import-chrome-cookies to t, and the EAF browser will automatically import cookies from Chrome.

You don't need to login separately in Chrome and EAF browser.

这个默认就导入，cookie多了不会卡吗？

eaf-browser-auto-import-chrome-cookies 默认是 nil，设置会 t 自动导入。

每次只导入当前访问的域名的 cookies，一个域名下的cookies数量还是可控的。
