Non-volatile memory data repository pattern (#24356)
* First batch of eeconfig conversions. * Offset and length for datablocks. * `via`, `dynamic_keymap`. * Fix filename. * Commentary. * wilba leds * satisfaction75 * satisfaction75 * more keyboard whack-a-mole * satisfaction75 * omnikeyish * more whack-a-mole * `generic_features.mk` to automatically pick up nvm repositories * thievery * deferred variable resolve * whitespace * convert api to structs/unions * convert api to structs/unions * convert api to structs/unions * fixups * code-side docs * code size fix * rollback * nvm_xxxxx_erase * Updated location of eeconfig magic numbers so non-EEPROM nvm drivers can use them too. * Fixup build. * Fixup compilation error with encoders. * Build fixes. * Add `via_ci` keymap to onekey to exercise VIA bindings (and thus dynamic keymap et.al.), fixup compilation errors based on preprocessor+sizeof. * Build failure rectification.
