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.
