pyproject: remove settings that cause other uses of autopep8 to fail

While the ability to run `autopep8 .` to format Blender's Python code
is handy, the settings to perform this can conflict with other uses
of autopep8 (which editors may use to auto-format on save).

Some arguments now need to be passed in, e.g:

    autopep8 . --in-place --recursive --jobs=0

We'll likely include this in `make format` convenience target so the
details for invoking autopep8 shouldn't be an issue in the long term.
