Separate out language specific tooling

[einari]

We need to come up with an approach where we isolate language specific tooling.

For instance globals.js now have a method called getNearestCsprojFile(). This should not be there and we should come up with a pattern that enables us to have language specific information ready for the tasks needing without having to break the open/closed principle by having to add this code directly to a place like this.
