Context Mesh: Prepare a preview documentation set for an MVP

We need to prepare a preview documentation for a launch of Context Mesh during the API Summit. This means:
- Adding a landing page for Context Mesh
- Creating a getting started guide
- Most possibly adding a reference page with some overview of capabilities
- Adding a relevant product tile on the home page
- Updating site navigation (this is for @fabianrbz)
