build-and-deploy: prepare for UCRT64 packages

We plan on building Git for Windows against the more modern UCRT instead
of the old MSVCRT at some point in the future (Most likely Git 3.0). To
be able to do that we'll need to be able to create and publish UCRT64
packages. And to aid a smooth transition, we'll need to be able to
publish MINGW64 and UCRT64 packages in parallel for a little while.
Prepare our deployment workflow to deal with this.
