Apple: Improve handling of missing SDKs in CMAKE_APPLE_ARCH_SYSROOTS
Use `<arch>-SDK-NOTFOUND` instead of an empty string as a placeholder in
`CMAKE_APPLE_ARCH_SYSROOTS` for architectures whose SDK is not found.
This ensures the length of `CMAKE_APPLE_ARCH_SYSROOTS` matches the
length of `CMAKE_OSX_ARCHITECTURES`. It also makes the missing SDKs
more visible in the value.
Issue: #20534
