[gnome-games/wip/exalm/ds: 5/15] platform: Add get_savestate_type()

[Alexander Mikhaylenko <alexm src gnome org>]

commit 9e405ba9196bfd9cc031185df89b5c6ef8266b5a

    platform: Add get_savestate_type()
    
    This will be used in the next commit to allow platforms to have custom
    savestate types.
    
    Make the implementation in RetroPlatform virtual to allow overriding it
    for Nintendo DS later.
