Replace the QEMU debugger VM approach with a simpler setup that runs
WinDbg directly on a Windows host. Cloud Hypervisor exposes the guest
serial port on a UNIX socket, socat turns it into a TCP listener, and
the convey tool bridges the TCP endpoint to a named pipe that WinDbg
attaches to.
This drops the need for a second Windows VM and the socat SYSTEM shell
script wrapping.
