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

[leonardchan]

Summary

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.

 // This is used in some places for suppression checking, which we
 // don't really support for Fuchsia.  It's also used in UBSan to
 // identify a PC location to a function name, so we always fill in
 // the function member with a string containing markup around the PC
 // value.
 // TODO(mcgrathr): Under SANITIZER_GO, it's currently used by TSan
 // to render stack frames, but that should be changed to use
 // RenderStackFrame.
