This is the first draft of the implementation of [p6333](https://docs.carbon-lang.dev/proposals/p6333.html). The `build` subcommand shared logic with the `compile` and `link` subcommands, so I've moved some of the functionality in `compile` and `link` to shared `CompileDriver` and `LinkDriver` classes, respectively. This also required exposing the `CompileOptions` and `LinkOptions` subcommand structs for re-use. There's still some work to do on the proposal, most notably the package include automatic path resolution and import, and the refactors to `carbon compile`.
