Bug 291309 – Web Inspector: Debugger: add a way to step over `await` as though it was sync code

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

[Devin Rousso]

when debugging async code with `await` it's often more desirable to follow what's written in code (i.e. as if the `await` didnt exist) instead of the literal execution flow, especially since with `await` that can sometimes mean execution just stops

for example, continually "Step Over" from the `debugger` should (eventually) pause at the `"after"` instead of just nothing
```
(async function() {
    debugger;
    console.log("before");
    await (async function() { return 42; })();
    console.log("after");
})()
```
