tracing: remove sampling state profiler

As per discussion in [1] the tracing sampling state profiler is not used anymore.
The coverage of the TRACE_EVENT_SCOPED_SAMPLING_STATE macros became
poor over time and new alternatives came out (e.g., V8 sampling profiler).
The overall is sensible but should be re-approached in a more sustainable way.
More specifically, the new trace event filters could be leveraged to build a
sampling profiler on top of the existing TRACE_EVENT macros.
