The codegen pipeline converts the `daphne::ReturnOp` to the `func::ReturnOp` as some upstream MLIR passes expect a `func::ReturnOp`. We may want to remove `daphne::ReturnOp` completely, TBD.
Moves the `ManageObjRefsPass` to before the MLIR-based codegen pipeline. Adjusts a couple edge cases in `ManageObjRefsPass` that are not longer neccessary as the `InsertDaphneContextPass` now runs after the `ManageObjRefsPass`.
