CMake: Propagate largefile flags to all internal consumers
The large file flags in qmake land are set in the mkspecs/features/unix/largefile.prf file, which is loaded by qmake when a CONFIG += largefile entry is written by configure into qmodule.pri. This essentially makes them global flags for all private Qt targets because qmodule.pri is a global file loaded load(qt_build_config) Thus assign the flags onto the PlatformCommonInternal target instead of the PlatformModuleInternal one. One peculiarity though is that in qmake land these flags are also applied when building examples as part of the main Qt build. This is because qt_build_config loads qmodule.pri even for an example, because qmake sees it as part of the overall Qt build. The flags are not applied by qmake if the example is built in a different standalone build dir not part of the Qt buil dir. We don't do that in the CMake build, and thus examples will never have those flags.
