The esp-idf-configdep utility works as a compiler wrapper. It lets the
compiler compile the app and checks whether -MF option was used to
generate dependency files. If yes, it checks for sdkconfig.h dependency
in those files.
Target file depending on sdkconfig.h is then scanned for all CONFIG_*
occurrences and the dependency file is altered so that the given target
file is marked as "dirty" only if the config options it actually uses
are changed.
This ensures that after a configuration update, only affected files are
rebuilt, reducing incremental build times.
The compiler launcher mechanism is changed from RULE_LAUNCH_COMPILE
(Makefile-only) to CMAKE_*_COMPILER_LAUNCHER (generator-agnostic),
enabling launcher chaining (configdep -> ccache -> compiler).

GDB now is standalone tool separated from toolchain due to frequent updates.
Added installation tests for the new tool.
Tests are changed because they were wrong, see explanation:
esp32 objdump:
40084290 <esp_crosscore_int_send_yield>:
......
/builds/espressif/esp-idf/components/esp_system/crosscore_int.c:145
4008429c: 000090 retw
With previous GDB backtrace was:
#0 0x4008429c in esp_crosscore_int_send_yield (core_id=0) at /builds/espressif/esp-idf/components/esp_system/crosscore_int.c:144
This commit fixes the backtrace with the right line number:
#0 0x4008429c in esp_crosscore_int_send_yield (core_id=0) at /builds/espressif/esp-idf/components/esp_system/crosscore_int.c:145
Other tests changes have the same cause of fixing.
Closes https://github.com/espressif/esp-idf/issues/6334
riscv32-esp-elf toolchain (used for ESP32-C3) can also be used for
ESP32-S2 RISC-V ULP coprocessor.
This removes the riscv-none-embed-gcc toolchain which was originally
used for the ULP, and updates the docs and CMake files to use
riscv32-esp-elf.
Some flags are cleaned up and workarounds removed from CMake toolchain
file.
