This implements the missing feature `cir::setTargetAttributes`. Although other targets might also need attributes, this PR focuses on the CUDA-specific ones. For CUDA kernels (on device side, not stubs), they must have a calling convention of `ptx_kernel`. It is added here. CUDA kernels, as well as global variables, also involves lots of NVVM metadata, which is intended to be dealt with at the same place. It's marked with a new missing feature here.
