Bump the deployment target for the compiler to macOS 13.0
Bump the deployment target from macOS 10.13-aligned versions to macOS
13.0-aligned versions. This allows us to stop linking CoreFoundation
in the swift runtime, which was previously required for availability
checking. It also lets us align the deployment target on x86_64 with
arm64, which was 11.0. Finally, it is a prerequisite to being able to
build swift using the macOS 15 beta SDKs.
