cmake: Selectively enable -no_warn_duplicate_libraries for Xcode 15+ 

We can't make the choice of whether to enable no_warn_duplicate_libraries
or not based on the Xcode version Qt was built with, as the target flags
will propagate to our cmake integration tests, which we run on platforms
where we don't have Xcode 15.

Pick-to: 6.7
