We copied the whole module and its unit test into pytorch codebase. (https://github.com/NVIDIA/cutlass/blob/main/python%2Fpycute%2Flayout.py). We did change the indentation of code from 2 spaces to 4 spaces. And add lint suppressor to make mypy happy. Also we need to make changes to unit test to include ownership and use `run_tests, TestCase` so that the test gets picked up by CI.
