[Flight] Normalize Stack Using Fake Evals (facebook#30401)

Stacked on facebook#30400 and
facebook#30369

Previously we were using fake evals to recreate a stack for console
replaying and thrown errors. However, for owner stacks we just used the
raw string that came from the server.

This means that the format of the owner stack could include different
formats. Like Spidermonkey format for the client components and V8 for
the server components. This means that this stack can't be parsed
natively by the browser like when printing them as error like in
facebook#30289. Additionally, since
there's no source file registered with that name and no source mapping
url, it can't be source mapped.

Before:

Instead, we need to create a fake stack like we do for the other things.
That way when it's printed as an Error it gets source mapped. It also
means that the format is consistently in the native format of the
current browser.

After:

So this is nice because you can just take the result from
`captureOwnerStack()` and append it to an `Error` stack and print it
natively. E.g. this is what React DevTools will do.

If you want to parse and present it yourself though it's a bit awkward
though. The `captureOwnerStack()` API now includes a bunch of
`rsc://React/` URLs. These don't really have any direct connection to
the source map. Only the browser knows this connection from the eval.
You basically have to strip the prefix and then manually pass the
remainder to your own `findSourceMapURL`.

Another awkward part is that since Safari doesn't support eval sourceURL
exposed into `error.stack` - it means that `captureOwnerStack()` get an
empty location for server components since the fake eval doesn't work
there. That's not a big deal since these stacks are already broken even
for client modules for many because the `eval-source-map` strategy in
Webpack doesn't work in Safari for this same reason.

A lot of this refactoring is just clarifying that there's three kind of
ReactComponentInfo fields:

- `stack` - The raw stack as described on the original server.
- `debugStack` - The Error object containing the stack as represented in
the current client as fake evals.
- `debugTask` - The same thing as `debugStack` but described in terms of
a native `console.createTask`.
