Add sound volume when unfocused setting (#14083)

Browse source 
This adds a new setting to set sound volume multiplier when Minetest window is unfocused/inactive (sound_volume_unfocused, located in Settings > Graphics and Audio > Audio > Volume when unfocused).

If the window is not focused, the sound volume will be multiplied by sound_volume_unfocused setting. The sound volume will be set back to sound_volume again when the window is focused.
