This is the last piece to bring together writing DXContainer files containing DXIL through the DirectX backend. While this change only has one test, all of the tests under llvm/test/tools/dxil-dis also exercise this code. With this change the output object file type for the dxil target is now DXContainer. Each of the existing tests will generate DXContainer files, and the dxil-dis tests additionally verify that the DXContainers generated are well-formed and can be parsed by the DirectXShaderCompiler tools. Depends on D127153 and D127165 Differential Revision: https://reviews.llvm.org/D127166
