Remove deprecated distutils (Python >=3.12)

[kvrigor]

Solves first TODO item in #406. Summary of changes:

• Removed finalize_options() since this method does not differ from its base class implementation, therefore making the override unnecessary.
• For run(), it's sufficient to call the base class run() and then add the custom pyccel commands.
• sub_run() should throw an error instead of failing silently (check=True).
• Formatted code to conform with Pylint and PEP8 checks

Can we do something about warning no. 3 at least?

Upon closer inspection it appers that this warning is not caused by Psydac, but rather by one of its dependencies. So please ignore this comment.
