Delete stacktrace profiler now that it's clearly dead.
Summary:
The only thing that still references any symbol out of stacktrace-profiler.h is in admin-request-handler.cpp, setting the std::atomic<bool> enable_stacktrace_profiler to true when you hit the /start-stacktrace-profiler endpoint. This is useless now that nothing actually instantiates any of the profilers.
Delete this last remaning reference, stop including stacktrace-profiler.h in other files where it wasn't actually used, and then delete hphp/util/stacktrace-profiler.{h,cpp} entirely.
