Pass focusedOption to the MenuList

[sunniejai]

This is useful for when you're overriding MenuList with a virtualized list (react-virtualized). You will need to know the focusedOption so that you can handle scrolling the virtualized list.

Now it's possible to do something like this in MenuList:

class MenuList extends React.PureComponent {
    componentDidUpdate(prevProps) {
        const { focusedOption } = this.props
        const previousFocusedIndex = getIndex(prevProps.focusedOption)
        const focusedOptionIndex = getIndex(focusedOption)
        if (previousFocusedIndex != focusedOptionIndex && this.listRef) {
          this.list.scrollToRow(focusedOptionIndex)
        }
    }
    ...
}

Quick question: Would this cause any additional re-renders passing in this option to the menu?
