// Sets up Group items for the actual resolving stage. Responsibilities:
//   - Moving Group items located in modules over to the product.
//   - Identifying groups declaring target artifacts and marking them accordingly.
//   - Setting up group-level module instances to ensure proper resolving of per-group module
//     properties.
//   - As a side effect of the above point, collecting all properties set on the Group level
//     to help the ProjectResolver decide which properties need to be re-evaluated at all,
//     which is an important optimization (see commit 9cd8653eef).
