Bug 291670 – Web Inspector: Debugger: preserve the pause reason and data when stepping over `await`

• Status: RESOLVED
• Resolution: FIXED
• Component: Web Inspector

[Devin Rousso]

currently the pause reason section of the navigation sidebar in the Sources Tab is empty when stepping over the `await` in code like
```js
(async function() {
    debugger;
    console.log("before");
    await (async function() { return 42; })();
    console.log("after");
})()
```

it should show "Debugger Statement" as the pause reason with the debugger breakpoint next to it so that the developer can see why the pause happened in the first place
