esp32: SEGGER SystemView Tracing Support 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

IDF provides useful feature for program behaviour analysis: application level tracing. It is implemented in the corresponding library and can be enabled via menuconfig. This feature allows to transfer arbitrary data between host and {IDF_TARGET_NAME} via JTAG interface with small overhead on program execution.

Developers can use this library to send application specific state of execution to the host and receive commands or other type of info in the opposite direction at runtime. The main use cases of this library are:
