LOG: [compiler-rt][hwasan] Add definition for Symbolizer::SymbolizeFrame

This is undefined if SANITIZER_SYMBOLIZER_MARKUP is 1, which is the case for
Fuchsia, and will result in a undefined symbol error. This function is needed
by hwasan for online symbolization, but is not needed for us since we do
offline symbolization.
