vscode-lib: expose vscode API via global

Currently vscode doesn't support dynamic imports, so it isn't possible
for a javascript provider to opt-in to more advanced user experience via
the vscode APIs.

Until we can more easily opt-in to vscode support, we expose the vscode
API via node's global object. We want to see what sort of APIs get used
from vscode in providers, and will then likely evolve a first class
editor abstraction.
