[Enhancement] Select which games you want to sync data

[playeremers]

You can select any games you want to delete game data on cryo but you can't do such a thing when you want to sync data between internal and microsd. The user needs to sync all games or they will not be able to sync at all.

Giving the option do select which games you want to sync data lets you "min/max" your internal storage and microsd. Useful if you got the 64GB deck + low storage microsd (or multiple low storage microsd cards).
