Add `_unsafe_debug` flag to serve options

[jpwilliams]

Summary

Adds an _unsafe_debug flag to serve options so that users can debug some finer details around their served functions.

import { functions, inngest } from "@/inngest";
import { serve } from "inngest/next";

export const { GET, POST, PUT } = serve({
  client: inngest,
  functions,
  _unsafe_debug: true,
});

It will log extra data to the console:

_unsafe_debug: _unsafe_debug: { isEdge: true }
_unsafe_debug: Returning isProduction: { isProd: false }
_unsafe_debug: isEdge; returning URL: {
  'req.url': 'http://localhost:3000/api/inngest',
  ret: 'http://localhost:3000/api/inngest'
}
_unsafe_debug: Returning method: { method: 'GET' }
_unsafe_debug: isEdge; returning header: { host: 'localhost:3000' }

It will also provide more details when responding to a GET request:

{
    "message": "Inngest endpoint configured correctly.",
    "hasEventKey": true,
    "hasSigningKey": false,
    "functionsFound": 1,
    "_unsafe_debug": {
        "url": "http://localhost:3000/api/inngest",
        "method": "GET",
        "isProd": false,
        "skipDevServer": false,
        "host-header": "localhost:3000"
    }
}
