EEPROM library: Move #include of Arduino.h to header file (espressif#1641)

EEPROM.h uses data types which are declared through Arduino.h but that file does not contain an #include directive for Arduino.h. This does not cause any problems when the EEPROM library is #included from a .ino file because the Arduino IDE automatically adds an #include directive for Arduino.h but this is not the case for .cpp files. If a .cpp file has an #include directive for EEPROM.h that does not follow an #include directive for Arduino.h then compilation fails:
