[CMake] Cleaning up flags for Darwin builtins

* Setting CMAKE_*_FLAGS_${BUILD_TYPE} isn't really needed since we're setting the same value everywhere
* functions sanitize variables differently from macros, darwin_add_embedded_builtin_libraries should be a macro otherwise it won't alter the variables.
