Brings up the Windows vhost-user GPU, when there is a vhost-user flag.

- Creates backend and VMM configs in broker.
- Always passes the VMM config to the main process.
- Passes backend config either to main or the vhost-user process.
- Create exit read / write event pair in broker, so GPU can request it
from its process (on Windows, when we close the rendering window).
