The issue this workaround set out to address has been resolved in
buildx for some time; there is no longer a need to preserve it.

It has been observed that the DiagTrack service in the pause
image is consuming a non-trivial amount of CPU. We don't need
this service in the pause image, so we should disable it.
We can disable the service by running chntpw in a docker buildx Linux stage
and then copy the SYSTEM file back to the final Windows image.

We can use docker buildx in order to build and push Windows images from the same Linux
node, as long as the Dockerfile does not have any RUN commands in the Windows step.
We also need to create a non-default builder instance in order to be able to
build and push Windows images.
The Windows images have to be built and pushed directly to the registry. Because of
this, the make target "push" has been removed (the target "all" will build and push
the images).
We need wincat for a few kubectl proxy scenarios.
For Windows containers without Hyper-V isolation, the host OS Version and the
Container OS Version need to match, which is why we added multiple Windows OS Versions
to the building process.
Adds support for Windows OS Versions: 1809, 1903, 1909, 2004.
Bumps pause image version to 3.4.
