Reorganize the tracing documentation so esp_trace is the master
component, with app_trace, SystemView, and Gcov referenced from it.
(cherry picked from commit 6c6490d54c)
The hw-reference/modules-and-boards page was removed from esp-idf docs
and moved to esp-dev-kits. The ESP32-S2-Saola-1 user guide similarly
moved. The configure-builtin-jtag link used the now-obsolete chip-less
stable URL format.
