Bundle plugin into a VS Code extension

[mjbvz]

We have an experimental means for a VS Code extension to contribute TypeScript plugins. This would have a few benefits:

1. Simplified installation
2. No jsconfig or tsconfig configuration required.
3. No need to npm install the plugin into each workspace or put it in your package.json
4. Will work with loose js/ts files (files that are not part of any js/tsconfig project)
5. Extension can also contribute other goodness, such as syntax highlighting

To be clear, the TypeScript server plugin itself would continue to work across all editors that use the TypeScript language service. This issue merely tracks bundling up the plugin into a VS Code extension

Here's a prototype: https://github.com/mjbvz/vscode-styled-components-extension

Requires a build of VS Code with microsoft/vscode@1bfad13
