[sanitizer_common] Fuchsia-specific symbolizer

Summary:
Fuchsia doesn't support built-in symbolization per se at all.
Instead, it always emits a Fuchsia-standard "symbolizer markup"
format that makes it possible for a post-processing filter to
massage the logs into symbolized format.  Hence, it does not
support user-specified formatting options for backtraces or other
symbolization.
