Fix Invalid Console Handle

[thomhurst]

In some consoles, the output is redirected.

There's a call to ResetLineCore which moves the Console cursor, but this won't work on a redirected console.

A simple check around it to see if the console has been redirected fixes this, otherwise it throws an error.

I've added some tests, and I've also added a Windows agent github action dev build, as that's where I was seeing my issue.

Thanks
