Make REACTOR_EMIT_DEBUG_INFO work on Windows and add "print on emit" support

- Use boost::stacktrace instead of libbacktrace so that we get can get
  callstacks on Windows as well. Note that on non-Windows, we tell
  boost::stacktrace to use libbacktrace.

- REACTOR_EMIT_DEBUG_INFO can now be enabled on all platforms

- Fix RR_LOG not building on MSVC by using __FUNCSIG__ instead of
  __PRETTY_FUNCTION__.

- Enable CMake option REACTOR_EMIT_PRINT_LOCATION so that EmitLocation
  in LLVMReactorDebugInfo.cpp injects printfs with func/file/line.
