Release Notes:

- N/A

As https://github.com/zed-industries/zed/discussions/24260 I mentioned
issue.

Make a complex data table example to test the text rendering
performance.

This example also can be an example to show how to build a large data
table.

```bash
cargo run -p gpui --example data_table
```

I will try to do some test. 

For example: With a threshold for the hold number of caches in
`FrameCache`, and only when the threshold is greater than a certain
number, some caches are released, or when a certain time has passed. I
am not sure if this is feasible.

This example is added to help us to test.
