Implement mii:u and mii:e entirely (#955)
* Implement mii:u and mii:e entirely

Co-authored-by: AcK77 <Acoustik666@gmail.com>

This commit implement the mii service accurately.

This is based on Ac_k work but was polished and updated to 7.x.

Please note that the following calls are partially implemented:

- Convert: Used to convert from old console format (Wii/Wii U/3ds)
- Import and Export: this is shouldn't be accesible in production mode.

* Remove some debug leftovers

* Make it possible to load an arbitrary mii database from a Switch

* Address gdk's comments

* Reduce visibility of all the Mii code

* Address Ac_K's comments

* Remove the StructLayout of DatabaseSessionMetadata

* Add a missing line return in DatabaseSessionMetadata

* Misc fixes and style changes

* Fix some issues from last commit

* Fix database server metadata UpdateCounter in MarkDirty (Thanks Moose for the catch)

* MountCounter should only be incremented when no error is reported

* Fix FixDatabase
