Rename "RyuFs" directory to "Ryujinx" and use the same savedata system the Switch uses (#801)

Browse source 
* Use savedata FS commands from LibHac

* Add EnsureSaveData. Use ApplicationControlProperty struct

* Add a function to migrate to the new directory layout

* LibHac update

* Change backup structure

* Don't create UI files in the save path

* Update RyuFs paths

* Add GetProgramIndexForAccessLog

Ryujinx only runs one program at a time, so always return values reflecting that

* Load control NCA when loading from an NSP

* Skip over UI stats when exiting

* Set TitleName and TitleId in more cases. Fix TitleID naming style

* Completely comment out GUI play stats code

* rebase

* Update LibHac

* Update LibHac

* Revert UI changes

* Do migration automatically at startup

* Rename RyuFs directory to Ryujinx

* Update RyuFs text

* Store savedata paths in the GUI

* Make "Open Save Directory" work

* Use a dummy NACP in EnsureSaveData if one is not loaded

* Remove manual migration button

* Respond to feedback

* Don't read the installer config to get a version string

* Delete nuget.config

* Exclude 'sdcard' and 'bis' during migration
