wrangler types - Import correct types for bound services

[eastlondoner]

I created this based on some DMs with Cloudflare Team members. Apologies for not creating an issue or discussion.

what this does

If extra wrangler configs are provided to wrangler types as:

wrangler types --service-config path/to/worker-a/wrangler.toml --service-config path/to/worker-b/wrangler.toml

This will use those to find the type definitions for the bound service, matching on the service name where it exists.

I took inspiration from the wrangler dev command which already allows passing in multiple wrangler files to then determine the locations of the implementations of each of the bound services on Env.

and I took inspiration from the DurableObject binding code already in the type generation

Now my generated types have all the correct methods attached.

@eastlondoner Thanks for this PR! I've modified it slightly to support Durable Objects, add tests, and to use the Service type for entrypoint bindings.

Also there are some lint checks failing

Thanks so much @petebacondarwin and @penalosa, this is amazing!
It looks like you've done everything - is there anything else that you'd like from me?

Thanks to you @eastlondoner for kicking this off. Given that @penalosa has added quite a lot, it would be good if you could try it out for yourself to check we have covered everything from your side.
