CMakeLists: Migrate from set_cpp_flag to per-project settings.

set_cpp_flag affects everything, including 3rd party code. We need to perform this separation as 3rd party code has unfixed warnings that we want to check for in our code. This also has the added benefit that we can use build switches (DCHECK_ALWAYS_ON, REACTOR_EMIT_DEBUG_INFO) without requring a full rebuild of LLVM.
