feat(shim): invoke local turbo version via npx if not installed (#8385) ### Description I highly recommend reviewing the first 4 commits on their own as they are primarily breaking up the massive `shim` module. This PR adds fallback option when global turbo doesn't find a local turbo install. If a local install isn't found we will look at: - lockfiles - package.json - turbo.json to identify if turbo 1 is expected If one of those result in finding a version of `turbo`, then we'll invoke `turbo` via `npx` to download the correct version on the fly. This behavior can be disabled with by setting `TURBO_DOWNLOAD_LOCAL_DISABLED` to `1` or `true` ### Testing Instructions Added unit tests for detection behavior. Manual testing of repos with/without a local install of `turbo`.
