Chrome DevTools Extensions has a silly problem where they block access
to load Resources from all protocols except [an allow
list](https://github.com/ChromeDevTools/devtools-frontend/blob/eb970fbc6482f281b95bbec1c33c1c539f6d50f0/front_end/models/extensions/ExtensionServer.ts#L60).

https://issues.chromium.org/issues/416196401

Even though these are `eval()` and not actually loaded from the network
they're blocked. They can really be any string. We just have to pick one
of:

```js
'http:', 'https:', 'file:', 'data:', 'chrome-extension:', 'about:'
```

That way React DevTools extensions can load this content to source map
them.

Webpack has the same issue with its `webpack://` and
`webpack-internal://` urls.

We currently throw away the Error once we've used to the owner stack of
a Fiber once. This maybe helps a bit with memory and redoing it but we
really don't expect most Fibers to hit this at all. It's not very hot.

If we throw away the Error, then we can't use native debugger protocols
to inspect the native stack. Instead, we'd have to maintain a url to
resource map indefinitely like what Chrome DevTools does to map a url to
a resource. Technically it's not even technically correct since the file
path might not be reversible and could in theory conflict.
