Refactor the ESP32 target SOCs together with all related boards. Most braking changes includes: - changing the CONFIG_SOC_ESP32* to refer to the actual soc line (esp32,esp32s2,esp32s3,esp32c3) - replacing CONFIG_SOC with the CONFIG_SOC_SERIES - creating CONFIG_SOC_FAMILY_ESP32 to embrace all the ESP32 across all used architectures - introducing CONFIG_SOC_PART_NUMBER_* to provide a SOC model config - introducing the 'common' folder to hide all commonly used configs and files. - updating west.yml to reflect previous changes in hal Signed-off-by: Marek Matej <marek.matej@espressif.com>
