Apple: Use CMAKE_EFFECTIVE_SYSTEM_NAME to share compiler info
Apple platforms macOS, iOS, tvOS, and watchOS can all share the same
compiler information. Rename `Darwin-*` modules to `Apple-*` and load
them all through `CMAKE_EFFECTIVE_SYSTEM_NAME`. This saves duplication
of 4 * 21 compiler information modules.
Issue: #17870
