devel/py-wheel: update to 0.40.0

[vishwin]

Summary

Switched to flit. Now allows setuptools itself to build under PEP-517, which will be required for Python 3.12.

While here, add this to setuptools's RUN_DEPENDS, since setuptools does not have wheel functionality of its own.

All OPTIONS removed due to circular dependencies.

Test Plan

exp-run to be requested, mostly to find transitive dependencies on setuptools
