This wires up dxil-op-lower, dxil-intrinsic-expansion, dxil-translate-metadata, and dxil-pretty-printer to the new pass manager, both as a matter of future proofing the backend and so that they can be used more flexibly in tests. A few arbitrary tests are updated in order to test the new PM path, and we drop the "print-dxil-resource-md" pass since it's redundant with the pretty printer.
