target/espressif: add application tracing functionality over JTAG

Browse Source 
This feature allows to transfer arbitrary data between host and
ESP32 via JTAG.

The main use cases:

1- Collecting application specific data
2- Lightweight logging to the host
3- System behaviour analysis with SEGGER SystemView
4- Source code coverage
