Bug 1403868 (part 2) - Tweak profiler_tracing(). r=mstange.

This patch does the following.

- Makes the TracingKind argument non-optional.

- Puts the UniqueProfilerBacktrace argument last in the second variant.

- Reorders AutoProfilerTracing to match the order of the profiler_tracing()
  declarations.
