Add some structs for files that DSi_NAND reads (#1842)

* Add DSiFirmwareSystemSettings

* Replace DSiFirmwareSystemSettings::TouchCalibration fields with std::arrays

- So assignment can be done in one line

* Make DSiFirmwareSystemSettings a union

- So its bytes can be accessed

* Add a comment

* Use DSiFirmwareSystemSettings instead of raw byte offsets

* Add definitions for DSiSerialData and DSiHardwareInfoN

* Move DSiFirmwareSystemSettings's hash update logic into its own method
