add parallels tools

[jrosengren]

Describe the package

Running Silverblue as a VM inside of Parallels on an M1 Mac, it would be great to have a way to install the Parallels Tools into the VM.

I did some googling and couldn't find an easy way to download these tools from the internet - Parallels seems to want you to get the ISO from the Parallels installation. I'm willing to provide them if needed, I don't want to put a link in the issue in case it violates Parallels terms of use (I don't know that it does, I just haven't looked)

Thanks!
