feat(launchpad): launch project and runner with graphql

[lmiller1990]

• Closes https://cypress-io.atlassian.net/browse/UNIFY-4 (Cypress internal team only)
• depends on chore: change ct -> component, projectType -> testingType everywhere for consistency #17461
• depends on chore(server): remove need to pass project object to Server#open #17435

Additional details

This PR builds on the GraphQL layer, adding queries and mutations to do things like:

• initialize plugins
• add a project
• initalize server/websockets
• launch/close a runner
• query for the config (WIP - only some options are exposed at the moment)

TODO: tests - I will write many tests once I get a review and make sure the architecture and design is heading the right direction.
TODO: Integrate with UI using Apollo - I will do it in another PR to keep the PRs small.

I need a very thorough review, since I am sure I'm not using GraphQL to it's fullest potential. Some general questions, mainly for @tgriesser

• we now have two sources of truth for some types, like Browser, which is defined in cypress.d.ts as well as here using Nexus' objectType. Should we be making Nexus definitions the one and only source of truth now?
• general review, I am still learning GraphQL and Nexus, I am probably doing some silly things. Eg, how best to handle errors? Current I am doing it like this.

Here is a demo, showing how I can launch the CT runner using the GraphQL layer. Hooking it up to the UI with Apollo should be straight forward.

Demo:

How has the user experience changed?
