Add `builtins.addDrvOutputDependencies` End goal: make `(mkDerivation x).drvPath` behave like a non-DrvDeep context. Problem: users won't be able to recover the DrvDeep behavior when nixpkgs makes this change. Solution: add this primop. The new primop is fairly simple, and is supposed to complement other existing ones (`builtins.storePath`, `builtins.outputOf`) so there are simple ways to construct strings with every type of string context element. (It allows nothing we couldn't already do with `builtins.getContext` and `builtins.appendContext`, which is also true of those other two primops.) This was originally in #8595, but then it was proposed to land some doc changes separately. So now the code changes proper is just moved to this, and the doc will be done in that.
