* Added new Olimex boards

Added variants for ESP32-H2-DevKit-LiPo and ESP32-SBC-FabGL boards

* Changes on the ESP32-POE and POE-ISO

Added menu for selection of the:
1) PSRAM enabled/disabled
2) Flash size 4/16 MB
3) Flash mode QIO/DIO
4) Partition Scheme additional options

* Updated pins_arduino.h for ESP32 POE, POE-ISO and Gateway

Due to the latest changes in the ethernet library/examples (https://github.com/espressif/arduino-esp32/pull/9242) full package of definitions of the ethernet macros is for each board that has non-default values.
For POE and POE-ISO is added a preprocessor condition #if defined BOARD_HAS_PSRAM due to our specific hardware because GPIO 16 and 17 are in use when PSRAM is enabled.
