refactor(turborepo): Split up `Run` into `RunBuilder` and `Run` (#7681) ### Description We're going to need access to the `Run` struct in watch mode, but without the actual execution part. To facilitate this, I'm splitting it up into a `RunBuilder` that builds all of the necessary data structures and a `Run` that executes the build. ### Testing Instructions <!-- Give a quick description of steps to test your changes. --> Closes TURBO-2583
