Auto merge of #6352 - Eh2406:dell-copy, r=alexcrichton
remove clones made redundant by Intern PackageId This is a follow up to #6332. I used clippy to find all the places we called `.clone()` on a `PackageId` or where we passed `&PackageId`. Yes that touches 44 files and 400+ lines, that is way we wanted `PackageId` to be `copy`.
