While we have "button-{pressed,released}" events there's often the
desire to control sound for key presses of e.g. on screen keyboards too.
Add separate events for that.
This allows us to e.g. add a particular sound for OSK key presses and
OSKs can send this with an `important` hint so they're also usable
in silent mode.
