Add status code to server error

[dertieran]

I just went ahead and implemented it, but feel free to close this PR if you don't want this feature.

Closes #243

Not sure if the passed status code should be validate, mainly status >= 400.

Can we add some integration tests for this.. we can create a route with a component that renders the error message and status code in the JSX (you can catch the error in an ErrorBoundary)

Sure I just couldn't get the tests working on my system so I didn't add one 🙈 But I will check if I can get it to work 👍🏻

What was the problem with the tests? maybe I could help u debug.. check this guide out: https://github.com/solidjs/solid-start/blob/main/CONTRIBUTING.md

I'm running Arch Linux so the install command did not work

pnpm --filter solid-start-tests install:playwright

> solid-start-tests@ install:playwright
> playwright install --with-deps
BEWARE: your OS is not officially supported by Playwright; installing dependencies for Ubuntu as a fallback.
Installing dependencies...
Switching to root user to install dependencies...
sh: line 1: apt-get: command not found
Failed to install browsers
Error: Installation process exited with code: 127

But I got it working by running the command that got logged in the console, but I needed to run it inside of the test folder.

npx playwright install

I also needed to comment out this line, otherwise the test was always skipped.

test.skip(process.env.ADAPTER !== "solid-start-node");

(Not sure if this is needed, I just saw it in the other tests.)

I added the test in a new file so I can easily test it separately, I hope this is fine.

I also just noticed that you can't just throw a ServerError in an api route. It will result in an empty 500 error, I would have expected it to just work.

Also is there a way to make the page return with the error status code? I tried deferStream but it still returned with a 200. (Not very important, just was curious about it.)
