Figure out better way to minimize release artifact distribution

[ekilmer]

After #961 lands, we will be duplicating much of the same binary artifacts. While GitHub public repos technically have unlimited storage space, this still feels wasteful and is not good for scaling if any other features come up.

vcpkg isn't built like Homebrew to favor a pre-built cache of artifacts. This makes it difficult to distribute anything but a complete installation directory of vcpkg artifacts.
