android: Turn GameInfo into a class (#6494) 

By only loading data from disk when creating an instance of this new
class instead of on every method call, we save a lot of file open
operations, which due to SAF are very expensive. This should noticeably
speed up game list scanning.

No intended change in what metadata is shown.
