Add support for full-screen dialogs

**Is your feature request related to a problem? Please describe.**
Not sure if I've missed it but, it seems full-screen dialog are currently not supported.

**Describe the solution you'd like**
It would be great to support full-screen dialogs [as per MD3 spec](https://m3.material.io/components/dialogs/guidelines#007536b9-76b1-474a-a152-2f340caaff6f).

**Describe alternatives you've considered**
Tried to customise the existing `Dialog` to work full-screen dialog with messy results.

**Additional context**

首先阅读现有的 Dialog 组件以及链接的 Material Design 3 全屏对话框指南。确定当前 Dialog API 如何处理尺寸，并找出组件入口点以及覆盖对话框行为的测试。当全屏对话框按照所要求的规范得到一致支持，并且现有的对话框行为仍有测试覆盖时，即表示完成。
