[python3] Add feature deprecated-win7-support. (#16420) 
* [python3] Move /MACHINE into MSBuild file.

This prevents potential patch application conflicts.

* [python3] Add feature deprecated-win7-support.

This backports the fix for bpo-39401 from the Python 3.8 branch instead
of the one from the Python 3.9 branch, which dropped support for Windows
7.

* [python3] Bump port version.

* [python3] Fix goof in static patch that omitted pathcch.lib.

* x-add-version

* [python3] Revert trivial patch changes
