Remove legacy PortalWrapper

[QDyanbing]

背景

PortalWrapper 是早期 portal/body scroll lock 逻辑遗留下来的辅助组件。当前 Ant Design v6 相关链路已不再运行时使用该组件，下游 @rc-component/dialog 也已在 react-component/dialog#565 中将 GetContainer 类型改为从 @rc-component/util root 导入。

改动内容

• 移除 legacy PortalWrapper 组件及其文档示例。
• 将 GetContainer 类型直接保留在 src/index.ts 中导出。
• 精简 Portal 相关测试，仅保留 Portal 本体行为覆盖。
• 调整 Portal 中遗留注释，移除对 PortalWrapper 的引用。

验证

• npm test -- Portal.test.tsx
• npm run lint（仅保留既有 warning）
• npm run compile（仅保留既有 warning）
• npm test
• git diff --check

Poem

🐇 旧的传送门，轻轻关上门，
PortalWrapper 悄然谢幕离场，
GetContainer 化身一行类型，
注释更清晰，测试更轻盈，
兔子跳一跳，代码更简洁！ ✨
