docs: Update stderr and simple backend, add systemtap backend

The following additions to the tracing documentation are included:

1. Move "stderr" backend documentation to top-level and out of "simple"
   backend.  Include hints on when this backend is useful.

2. Document the "simple" backend thread-safety limitation.

3. Document the "dtrace" backend for SystemTap.
