[wrangler] add connect wrangler config section

[ThomasRubini]

This PR adds a tcp_handlers config section, for the upcoming inbound TCP feature on Workers. It will configure workerd TCP listeners as implemented in cloudflare/workerd#6059

It would have to be set in the wrangler config like this:

{
	"connect": [{
		"protocol": "tcp",
		"port": 5432,
		"address": "127.0.0.1", // default
	}],
}

or in the new config format like this:

import { defineWorker, triggers } from "@cloudflare/config";

export default defineWorker({
  triggers: [triggers.connect({ protocol: "tcp", port: 5432, address: "127.0.0.1" })],
});

I'd love feedback on the tcp_handlers name. Please also note that UDP handlers are planned, so if this name is merged, it would probably also mean adding a udp_handlers section in the future.

Looks good to me, although an option for this should also be added to the programmatic wrangler config

[ThomasRubini]

I think the test failures are unrelated to my changes. Could someone from the team confirm ?

yes, they are not, CI's been quite flaky lately 😓

Feels free to ignore them 👍

[dario-piotrowicz]

As I mentioned in my comment I really don't like the inclusion of "udp" here, besides that everything else looks good to me

[dario-piotrowicz]

Thanks a lot for the udp removal @ThomasRubini 🙏

Looks good to me 😄
