[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 😄

I squashed commits because I believe with the changes in direction and the rebase done, it would make more sense to avoid keeping the history of changes done and undone (and to help with potential future rebases)

no feature changes have been made with these force pushes, only rebases and resolving conflicts

[petebacondarwin]

Looks like this needs another rebase, sorry.
