Devtools: initial Debugger > Sources panel (#36164)

Browse source 
This patch adds support for listing scripts in the Sources panel.
Classic scripts, both external and inline, are implemented, but worker
scripts and imported module scripts are not yet implemented.

For example:

```html
<!-- sources.html -->
<!doctype html><meta charset=utf-8>
<script src="classic.js"></script>
<script>
    console.log("inline classic");
    new Worker("worker.js");
</script>
<script type="module">
    import module from "./module.js";
    console.log("inline module");
</script>
<script src="https://servo.org/js/load-table.js"></script>
```

```js
// classic.js
console.log("external classic");
```

```js
// worker.js
console.log("external classic worker");
```

```js
// module.js
export default 1;
console.log("external module");
```
