Please allow opt-out of passive event handlers for touchstart, touchmove, and/or onscroll events

[finnbear]

I'm trying to call prevent_default on a touchstart event because I think might stop the vibration motor from buzzing when my Yew app is loaded and touched within an Android WebView.

Right now, Yew enforces passive event handlers for these three events:

yew/packages/yew/src/html/listener/events.rs

Lines 207 to 213 in dbdd3b7

	// Best used with passive listeners for responsiveness
	impl_passive! {
	onscroll(Event)
	ontouchmove(TouchEvent)
	ontouchstart(TouchEvent)
	}

Ideas

• Feature flag, on by default, that makes these passive
• Some way to configure whether the listener is passive on a per-listener basis
