HLE: Fix Mii crc generation and minor issues (#5766)

* HLE: Fix Mii crc generation

Validating CRCs for data and device involves calculating the crc of all data including the crc being checked, which should then be 0.

The crc should be _generated_ on all data _before_ the crc in the struct. It shouldn't include the crcs themselves.

This fixes all generated miis (eg. default) having invalid crcs. This does not affect mii maker, as that generates its own charinfo.

Does not fix MK8D crash.

* Fix other mii issues

* Fully define all fields for Nickname and Ver3StoreData

Fixes an issue where the nickname for a mii would only have the first character on some method calls.

* Add Array96 type
