Move more fields out of Config

[gsoltis]

Commits:

1. Move RootPackageJSON out of Config. Only run and prune need it
2. Move calculateGlobalHash and associated code into the run package. Only run needs it, and it is unrelated to the package-dependency graph
3. With calculateGlobalHash gone, update WithGraph to no longer need TurboJSON and Config, replaced with repoRoot.
