Don't make EEPROM size assumptions with dynamic keymaps. (#16054)

Browse source 
* Don't make EEPROM size assumptions with dynamic keymaps.

* Add support for checking against emulated flash, error out if someone attempts to build a board without specifying EEPROM size.

* Reorder defines so that MCU is considered last.

* Refactor EEPROM definitions for simplicity.

* Fix max sizing of kabedon/kabedon980.

* Fix max sizing of mechlovin/olly/jf.

* Fix unit tests.

* Review comments, add messages with values during build failures.

// The EEPROM is really RAM with a hardware-based backup system to
// flash memory. Selecting a smaller size EEPROM allows more wear
// leveling, for higher write endurance. If you edit this file,
// set this to the smallest size your application can use. Also,
// due to Freescale's implementation, writing 16 or 32 bit words
// (aligned to 2 or 4 byte boundaries) has twice the endurance
// compared to writing 8 bit bytes.
