Rewrite `socket_vmnet` in Go and integrate it to `lima-privileged-net`

Now we have two privileged network drivers:

• socket_vmnet for macOS hosts (https://github.com/lima-vm/socket_vmnet)
• lima-privileged-net for Linux hosts (https://github.com/lima-vm/lima/pull/5483)

The functionality of socket_vmnet should be rewritten in Go and merged to lima-privileged-net to cover both macOS and Linux in a single driver.
