Remove MANIFEST.in; Migrate to pyproject.toml

With the use of setuptools_scm, all files that are tracked with the version control system will be included in the distribution anyway -- so there's no need to declared "graft/include" in the MANIFEST.in.

The side effect of completely remove MANIFEST.in is the egg-info will be included. As setuptools can't be configured to prune src/spdx_tools.egg-info via pyproject.toml config.
But the inclusion of egg-info is actually a standard practice (setuptools itself also include this information). The additional size of sdist when include the egg-info is 5.6 kbytes (704,357 vs 698,744 bytes).

If needed, we can also include a minimal MANIFEST.in with one line:

prune src/spdx_tools.egg-info

to exclude the egg-info from sdist
