## Message

```
Refactor TextLayout to use Rc<RefCell> instead of Arc<Mutex> for improved performance (#27177)

Since `TextLayout` is not shared by multiple threads, changing it to
`Rc<RefCell<T>>` should improve performance.

I also found several codes with the same problem. If you think this
change is beneficial, I will continue to improve it in the subsequent
PR. 🙂

Release Notes:

- N/A
```
