remove _user_defined_size from EEPROM (espressif#5775)

Summary Related to the issue espressif#5773 and espressif#2280. _user_defined_size is removed from EEPROMClass because it is redundant in the current code EEPROMClass::length() returns _size that is the true available size of EEPROM Impact _user_defined_size is removed from EEPROMClass EEPROMClass::length() returns _size that is the true available size of EEPROM
