Subject: [PATCH] [windows][build.ps1] only use
 swift-corelibs-foundation-windows checkout in CI

https://github.com/swiftlang/swift/pull/75073 has broken a local
toolchain build on windows using build.ps1,
as the local build does not use update_checkout on windows, and
thus does not checkout swift-corelibs-foundation-windows.
