nintendo-ds: Add NintendoDsRunner
Add a proxy around RetroRunner that uses game_init() and game_deinit()
signals to track game state and set desmume_screens_layout option
according to gsettings.
Also implement get_extra_widget() to return a NintendoDsLayoutSwitcher.
Use R3 and Ctrl+S as shortcuts for swapping screens in quick switch mode.
