Log:
[CMake] Abstract Config.h generation for Xcode
This patch abstracts the generation of Config.h and creates a dummy project
entry point to allow generation of LLDB's Config header without performing a
full CMake configuration.
This will enable the Xcode project to generate LLDB's Config header.
