cpu/esp32: cleanup used linker scripts

Browse Source 
The cleanup reduces the number of linker scripts used for the ESP32x ROMs and thus the symbols used from the ESP32x ROMs. It works with both gcc 12.2 and gcc 14.2. The latter gcc version is a prerequisite for ESP-IDF v5.2 and higher and thus a prerequisite for starting the work on the RIOT-OS port for the latest version of ESP-IDF.
