Automate the generation of platform specific bindings

[joedevivo]

Currently there's ./native in the project root, which contains bindings that I've manually built on three different physical computers. Not even VMs!

I have an idea that would involve a new repo which only contains the dependencies I need with native bindings (currently @serialport/bindings & drivelist), and then use azure pipelines matrix strategy to generate a release for each platform, then download all of those releases as part of this extension's packaging.

Look into how they did it for Arduino microsoft/vscode-arduino#982
