ActionList.Item: Check defaultPrevented between onSelect & afterSelect

[siddharthkp]

• Closes <ActionList.Item>: event in onClick can be canceled, but it cannot be canceled in onSelect #3162
• Implements @gr2m's changes from fix: prevent closing menu when event.preventDefault() is called on ActionList.Item's onSelect handler #3163

---

Context: Today, if you want to customize the behaviour of a menu after selection (like in the video below) you have to opt out of onSelect and implement it yourself using onClick and onKeypress

As you can imagine, this can create bugs if not done well. This PR adds the ability to prevent the default behavior after onSelect by calling event.preventDefault inside it. (See newly added story for example)
