Arduino integration - Verify/Compile

[shizn]

The users should have installed Arduino IDE before they try this extension. The extension will provide a F1 task - Verify. Basically it will run a local excitable command like below.

• Windows: arduino.exe --verify [sketch path] -v

We don't support Linux distros and macOS in this sprint.

The code logic for Windows is already checked in. Close this one and will open separate issue for Mac.
