GraphQL API Initial Implementation

- Build API via annotations using HotChocolate.
  - Export to `artifacts` on build.
  - Repurpose REST API types where possible, but many have to be reimplemented.
  - Transfer controller and bridge controller will definitely have to stay forever.
- Added `Tgstation.Server.Client.GraphQL` built from schema using StrawberryShake.
  - Added equivalent server information query.
- Setup semver and u32 (de)serialization.
- Begin transitioning to multi-client type live tests.
- Add GraphQL route `/api/graphql`
- Rename ServerClient likes to RestServerClient equivalent.
- Major API/Client library version bumps.
