Window Controls: Add Windows style

[ThaDaVos]

Currently the Window Controls only allow to show OSX based controls - I would love to also see Windows based controls, just like Carbon has (as this project is inspired by it and I've found this project by searching for a Carbon Extension in VSCode which there isn't)

Agree, would be great to have alternatives to macOS 👍
