tracer: declare GstTracer API stable

Merged Tim-Philipp Müller requested to merge tpm/gstreamer:tracer-api-stable into master

It's been around for more than 4 years and people have built lots of stuff on top of it, doesn't really make sense to keep it marked as unstable. We're unlikely to change it now, and we can always deprecate it and make a new one if needed.

This stabilises the following API:

  • gst_tracer_register()
  • gst_tracing_get_active_tracers()
  • gst_tracing_register_hook()
  • gst_tracer_record_new()
  • gst_tracer_record_log()

Might also help a bit with #424 (closed)
