The core of the problem is that we're unable to create a window for the
console. For CI, it may be good to simply use null display driver, something
like this should do:

wine reg add 'HKCU\Software\Wine\Drivers' /v Graphics /t REG_SZ /d null /f

We don't use it as an implicit fallback under the assumption that in most case
it user error that we want to make verbose. We could achieve a similar effect
just for consoles by ignoring CreateWindow() failure in conhost.
