  -----------
  [sanitizer] Fail __sanitizer_symbolize_demangle instead of returning input (#66006)

LLVMSymbolizer::DemangleName returns the same input if it can't
demangle.
We can't tell if this is already demangled or format is unsupported.

Internally DemangleName uses nonMicrosoftDemangle which can report a
failure.
