gpui: Improve window.prompt to support ESC with non-English cancel text on macOS (#29538)

Release Notes:

- N/A

----

The before version GPUI used `Cancel` for cancel text, if we use
non-English text (e.g.: "取消" in Chinese), then the press `Esc` to cancel
will not work.

So this PR to change it by use `PromptButton` to instead the `&str`,
then we can use `PromptButton::cancel("取消")` for the `Cancel` button.

Run `cargo run -p gpui --example window` to test.

---

Platform Test:

- [x] macOS
- [x] Windows
- [x] Linux (x11 and Wayland)
