utils.registerEventHandler: accept options parameter which is passed to
addEventListener. This allows to register passive event handlers.
event binding: add `${eventName}Passive` binding to decide if
`${eventName}` handler should be passive. This works in the same way as
`${eventName}Bubble` binding.
utils.canUsePassiveEventHandlers: set to true only if `addEventListener`
accepts third argument of type `{passive: true}` and it does not allow
to use `Event.preventDefault` method.
