[wrangler] Add vpc_networks binding support

[RiscadoA]

Fixes WVPC-172.

Adds vpc_networks binding support, allowing Workers to route traffic through a Cloudflare Tunnel. At runtime, env.MY_VPC.fetch("http://internal-host/") routes through the tunnel. Each binding generates a Fetcher type. Like vpc_services, these bindings are always remote in wrangler dev.

Network bindings are configured through either a tunnel_id or a network_id:

{
  "vpc_networks": [{ "binding": "MY_FOO_VPC", "tunnel_id": "your-tunnel-uuid" }]
}

{
  "vpc_networks": [{ "binding": "MY_BAR_VPC", "network_id": "some-network-id" }]
}
