caps: Implement SaveScreenShot calls and cleanup (#2140)

* caps: Implement SaveScreenShot calls and cleanup

This PR implement:
- caps:u IAlbumApplicationService (32) SetShimLibraryVersion
- caps:c IAlbumControlService (33) SetShimLibraryVersion
- caps:su IScreenShotApplicationService (32) SetShimLibraryVersion
- caps:su IScreenShotApplicationService (203/205/210) SaveScreenShotEx0/SaveScreenShotEx1/SaveScreenShotEx2

ImageSharp is used to save the raw screenshot data as a JPG file following what the service does.
All screenshots are save in: `%AppData%\Ryujinx\sdcard\Nintendo\Album` folder. (as example a screenshot file path will be `%AppData%\Ryujinx\sdcard\Nintendo\Album\2021\03\26\2021032601020300-0123456789ABCDEF0123456789ABCDEF.jpg`

This is needed by Animal Crossing: New Horizon where screenshots looks like this:

And this is needed in Monster Hunter Rise but screenshots are currently empty due to another issue.
