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.

The pause image is a 240KB image that simply pauses waiting on a signal.
Use this for the net container which only needs to act as a placeholder.
Current net image is ~2.5MB. From my tests, this reduces startup time
for the net container from ~14s to ~6s.
