esp32: SEGGER SystemView Tracing Support

Browse Source 
Implements support for system level traces compatible with SEGGER
SystemView tool on top of ESP32 application tracing module.
That kind of traces can help to analyse program's behaviour.
SystemView can show timeline of tasks/ISRs execution, context switches,
statistics related to the CPUs' load distribution etc.

Also this commit adds useful feature to ESP32 application tracing module:
 - Trace data buffering is implemented to handle temporary peaks of events load

ToDo: The multicore implementation of this uses taskENTER_CRITICAL etc to make sure the
queue structures aren't accessed by another processor or core. It would be useful to have
IRQs be able to schedule stuff while doing task-related stuff, meaning we have to convert
the taskENTER_CRITICAL stuff to a lock + a scheduler suspend instead.
