[issue12273] Change ast.__version__ calculation to provide consistent ordering

[Brett Cannon]

Brett Cannon <brett at python.org> added the comment:

sys.version_info and sys._mercurial provide all the info needed for someone (like me for mnfy) to know if their code will work against the AST nodes used by the running interpreter. I say drop __version__.
