Update debug wheels used on Windows.

[nuclearsandwich]

This updates the Debug wheels for Python 3.8.

In order to support builds of Dashing and Eloquent we'll need to come
back to this and add support for using a different set of wheels for the
older python version but this hopefully gets us the Windows debug nightlies back.

All I did was build up to ament_mypy in order to test that everything was installable.

Debug build:

Sanity non-Debug build:

I'm going to merge this PR in order to give the nightlies a chance. As mentioned there's outstanding work required to restore Dashing and Eloquent builds and these wheels could still cause problems during build or test but I'm willing to find that out in the next round of nightlies since this will at least not fail during pip install.

With this patch the debug job is now showing failures building rosidl_generator_py

I think our wheel was affected by numpy/numpy#16005
I used a workaround similar to the one proposed in that issue. If is successful I'll update the upstream issue with my exact workaround and try to figure out what a PR would look like to resolve the underlying issue.

That worked so I started a full build to try and catch the next things before nightlies.

My last build failed because I pre-emptively built the Cryptography wheel against OpenSSL 1.1.1 rather than 1.0.2. I am trying to run another without sros2 and test_security to avoid that particular break while I iterate on the OpenSSL 1.1.1 PR for Foxy.
