Adds new fastlane lanes: - `fastlane lint` which checks the linters - `fastlane autocorrect` which applies the linters which can autocorrect (Rubocop, SwiftFormat) Adds a build step to the Codegen abstract target which runs SwiftFormat in lint mode, pointing out what it's going to change when run. Applies SwiftFormat to nearly all code -- exempts a few externally-sourced files and generated code.
