As far as I can tell, this encapsulates what I had in-progress while I was working on getting Windows builds to work better in Docker containers. I had a Windows Kokoro machine running Docker that I used to test this, and was able to get builds working, but wasn't feeling certain about the configuration, and hadn't integrated anything with the CI system yet. I've included a lot of comments explaining what I was working on.

- One detail that's left out of the comments is that I'm not sure how the recent changes to the Pip package build process factor in to this.
- I removed a lot of bits from the Dockerfile that weren't necessary (this Dockerfile is based on Kokoro's Windows Dockerfile)
- I wasn't able to explicitly test this PR as-is, so it will probably need tweaking before it works.
