CPack: Avoid requiring Carbon framework on OS X (#16021)

In commit v3.5.0-rc1~232^2 (CPackDMG: Add support for multilingual SLAs,
2015-10-19) we added use of the Carbon framework in order to get access
to its APIs to convert Script Manager RegionCode values.  This is not
necessary.  Instead we can use CoreServices.

While at it, replace individual CoreFoundation includes with including
the entire framework, which is the correct way.
