Feature Request: Following #include statements

[philschenker]

Modern devicetrees have many includes and it is tedious to open them. I propose to have the feature of clicking with hold CTRL button on a dtsi include and vscode opens it. As far as I understand it currently this needs to be done by the extension that supports the respective "programming language".

I'd be willing to help get this up and running if you can point me into the right diretion.
