Add MANIFEST.in (pytorch#52908)

Summary:
Do not build PyTorch if `setup.py` is called with  'sdist' option
Regenerate bundled license while sdist package is being built
Refactor `check_submodules` out of `build_deps` and check that submodules project are present during source package build stage.

Test that sdist package is configurable during `asan-build` step
