feat(macOS): Support host DNS aliases for macos

[Kern--]

Issue #, if available:
macOS portion of #1079

Description of changes:
This change adds:

1. host.finch.internal
2. host.docker.internal

as DNS names that are aliased to the host's loopback address. This allows service and containers inside the VM to connect to services bound to the host's loopback device.

Testing done:
main.go

package main

import "net/http"

func main() {
        http.HandleFunc("/hello", func(w http.ResponseWriter, r *http.Request) {
                w.Write([]byte(`{"response": "ok"}`))
        })
        http.ListenAndServe(":8080", nil)
}

$ go run main.go

in another shell

$ limactl shell finch
$ curl host.finch.internal:8080/hello
{"response": "ok"}
$ curl host.docker.internal:8080/hello
{"response": "ok"}

Can a e2e test be added to run a container and ping the DNS aliases here?
