Add a `pyproject.toml` file that provides build system information for PEP 517-compliant builders. While all the commonly used builders provide fallback to running `setup.py` for backwards compatibility, this ensures the best forward compatibility. It also provides a reliable way of specifying the minimum required setuptools version. Effectively, it will make it possible to remove `setup.py` in favor of purely declarative configuration in the future, or even switch to a different build system. Update `setup.py` to explicitly add the current directory to `sys.path` for importing `lit`. This is necessary, as the modern setuptools backend does not guarantee that the current directory is present there. Differential Revision: https://reviews.llvm.org/D136976
