Tor Arne Vestbø e23ea6a5d3 cmake: Propagate Qt's CMAKE_OSX_SYSROOT to user projects by SDK name 
CMake will transform the CMAKE_OSX_SYSROOT into a path as part of
Darwin-initialize.cmake, as non-Xcode generators rely on it to
be a path when setting -isysroot.

When propagating the CMAKE_OSX_SYSROOT to consumers of Qt, we need
to propagate it by its original SDK name, so that CMake's Xcode
generator can write it by name into the SDKROOT Xcode setting by
name, and so that we don't lock the user into using the exact
same SDK path (and version) as we did when building Qt.

The QT_APPLE_SDK code path has been removed, as setting QT_APPLE_SDK
will always set the CMAKE_OSX_SYSROOT as well.
