feat: allow scrollable events

[gorhom]

Motivation

This PR will allow users to use onScroll, onScrollBeginDrag & onScrollEndDrag events on the scrollable components.

^ events should run on JS thread, no support for worklets, yet.

@gorhom Is there any reason not to also include the same type of logic for onMomentumScrollBegin and onMomentumScrollEnd? If not, happy to put up a quick pr for that.

Separately, what are your thoughts on including parallel config for allowing worklets like onScrollWorklet, onScrollBeginDrag, etc.? It's not perfect but possibly better than trying to detect if a passed onScroll function is a worklet or anything like that. Right now I've been modifying the handlers in useScrollHandler (via patch-package) to allow for worklets, but that's pretty messy too.

Kinda related, but it also looks like onScrollEndDrag might be called twice in the case when you also have momentum when lifting your finger on a drag.
