line_clamp to truncate text after a specified number of lines (#23058)
Release Notes:
- N/A
Add this feature for some case we need keep 2 or 3 lines, but truncate.
For example the blog post summary.
- Added `line_clamp` method.
Ref: https://tailwindcss.com/docs/line-clamp
## Break changes:
- Renamed `gpui::Truncate` to `gpui::TextOverflow` to match
[CSS](https://developer.mozilla.org/en-US/docs/Web/CSS/text-overflow).
- Update `truncate` style method to match [Tailwind
CSS](https://tailwindcss.com/docs/text-overflow) behavior:
```css
overflow: hidden;
text-overflow: ellipsis;
white-space: nowrap;
```

## Describe changes
The [second
commit](https://github.com/zed-industries/zed/commit/6b41c2772f9d1c5f4efe69fe83206a14407af4d4)
for make sure text layout to match with the line clamp. Before this
change, they may wrap many lines in sometimes. And I also make
line_clamp default to 1 if we used `truncate` to ensure no wrap.
> TODO: There is still a tiny detail that is not easy to fix. This
problem only occurs in the case of certain long words. I will think
about how to improve it later. At present, this has some flaws but does
not affect the use.
