Notes:
I removed the x86 lib/dll files as that's not a supported target for flutter desktop on windows.
WinSparkle 0.8.0 now ships with ARM64 lib/dll files as well, but I excluded those too since they wouldn't be used without other changes (which I'm not able to test as I don't have machine with ARM64)
