Make it easier to bundle @trpc/server

[esamattis]

Currently it requires two workarounds

1. The url module must be installed from npm since it is a Node.js build-in and cannot be bundled otherwise
2. Imports to http module must be ignored manually

With these workarounds I was able to bundle it with esbuild using this script

const ignorePlugin = require("esbuild-plugin-ignore");
require("esbuild").build({
    entryPoints: ["src/worker.ts"],
    bundle: true,
    outfile: "dist/worker.js",
    target: "chrome96",
    plugins: [
        ignorePlugin([
            {
                resourceRegExp: /http$/,
                contextRegExp: /.*/,
            },
        ]),
    ],
});

Why?

Bundling allows to run it non-node.js environments such as Cloudflare Workers, browsers, Remix in without node.js and possibly in Deno too.

Here's a proof of concept running it in a Cloudflare Workers https://github.com/esamattis/trpc-cloudflare-worker

What could be done?

The url module installation is OKish workaround but it would better to just get rid of it and use URLSearchParams instead which is available as a global in all these environments including Node.js.

The import { router } from "@trpc/server" should not end importing the http module. Only the adapter file using it should import it.
