chore: Upgrade GPUI 3 (#587)
The pervious version has keep on
[gpui2](https://github.com/longbridge/gpui-component/tree/gpui2) branch,
if there need to use.

Ref https://github.com/zed-industries/zed/pull/22632

## Prepare

### Generate index.scip

```bash
rust-analyzer scip ./ > index.scip
```

### Get [refactor](https://github.com/zed-industries/refactor)

```bash
https://github.com/zed-industries/refactor.git
```

## Refactor exist code

```bash
cd refactor
cargo run -- ~/work/gpui-component
```

Then will get result if successed:

```
    Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.03s
     Running `target/debug/refactor /Users/jason/work/gpui-component`
Loaded 115 SCIP documents
Processing files starting with focus path: ""
Changed 90 files
```
