LOG: [libcxxabi/demangle] Remove __cxxabi_config.h include (#101971)

The demangler is shared between libcxxabi and llvm/lib/Demangle, see
libcxxabi/src/demangle/README.txt. The copy in llvm/lib/Demangle cannot
use __cxxabi_config.h. Remove the include. It was only used to identify
clang, which can easily be done without the include as well.

No intended behavior change.

Removed:
