Desktop: Controller improvements - readable labels, controller hotkeys, option to apply profiles to all controllers (#1717)

* controller hotkey support and SDL refactor to use GameController API,
which adds more user-readable names to controller input maps

* Add "Press A (right) button" command to input automap that will map in nintendo layout if the user has a nintendo layout / prefers to match letters rather than position.

* honor shortcut context with controller hotkeys

* fix profiles not saving correctly

* analog_from_keyboard display fix, build error fix

* attempt to fix event_queue bugs

* Do not signal savestate if system is powered off
