Build fail on Windows

I try to use swift-foundtion in my package on Windows, and it give me these errors:

This is a regression due to the 72.1 upgrade. I've filed swiftlang/swift#70029 to track enabling CI for Windows. I don't see how to fix this. The changes have hardcoded a dependency on oslog. It is unclear to me how this builds on Linux.

Thanks. I think @iCharlesHu was looking into similar failures on Linux

@parkera, @iCharlesHu, @itingliu - any chance of getting a release with the changes to allow a bump in apple/swift-foundation? That should help get the Windows CI on track.

@compnerd we tagged 0.0.6: https://github.com/apple/swift-foundation-icu/releases/tag/0.0.6

swift-foundation has also been updated.
