ci/windows: Update build container image with all deps so wraps can be disabled

This will very slightly improve build times, but more importantly, it means that the build job doesn't need to reach out to the internet, which improves reliability and repeatability.

/cc @hakzsam regarding libelf - I had to make a change to the meson build definition for the Win32 port, but the current "maintainer" of that dep no longer wants to maintain it. I've pointed the dep at my fork with the necessary change, but we should consider if we really need to maintain RADV builds for Windows. If so, I'd appreciate if someone involved with RADV was able to take over that dependency.
