Summary
Related to the issue #5773 and #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
* Added convert method to transfer data from partition to nvs
* Could have sworn I changed the return when I made the label
* Empty state should be 0xFF. Fixed some logging levels
* Set result on success
* Converted EEPROM library to use nvs instead of partition. Removed eeprom partition from all partition table CSV files.
* Changed variable names, added some comments, formatting as per me-no-dev's requests
* Checks for memory on malloc
* Moved include nvs.h from header to code
* Reworked the extra example to make it more clear how to actually use the library and persist data
* add missing EEPROM lib to CMakeLists.txt, moved the EEPROM files to proper directory
