When building python using Visual Studio, the curses and curses.module, are not getting built.

[zooba]

The curses module is currently not supported on Windows, and this patch is far more than just updating the VS build. I've updated the title.

Refer to bpo-31951 for more context.

This will need more work than what's been done in the pull request, as _curses is still not being built as part of normal build, and so is not being tested in CI.

[erlend-aasland]

With the recently added Python REPL, we now have a use case for adding curses support on Windows.
