Migrate setuptools configuration inside pyproject.toml (ctypesgen#198)

* Migrate setuptools configuration inside pyproject.toml

* Remove mention of setup.py commands which are to be avoided

* Use version of setuptools and setuptools_scm recommended by setuptools_scm

* setuptools_scm 8.0.0 dropped support for EOL Python 3.7. Use latest from setuptools_scm 7 release

* Use `python -m build` in tox commands for packaging

* Use only `python -m build`

As recommended in https://packaging.python.org/en/latest/guides/publishing-package-distribution-releases-using-github-actions-ci-cd-workflows/

* Use only `python -m build` for Travis configuration
