input_server: Notify apps of new key map

Define a new message, B_KEY_MAP_LOADED, that is broadcast to applications by the Input Server each time a key map is loaded. This allows apps that cache key-map data to know when their copy has become stale. Change InputServer::HandleGetSetKeyMap() so it returns an error in the event loading even the system (fallback) key map fails.
