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

* 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.
