Combobox Suggestions

[just214]

I just tried out the combobox and found it to be really nice!

A few ideas:

• It would be nice to be able to pass a ReactNode to the Combobox.Input's displayValue so that you could display images, svgs, etc. Maybe a separate stringValue and displayName props so that a string is still being predictably used for the event target value?
• I found that you can wrap the Combobox.Input with the Combobox.Button to cause the list box to open without a state change. (example below) It would be nice if Combobox exposed a setOpen or toggleOpen render prop to allow for manual control of the open state. Use cases: Default open or open on focus.
• It would be nice to have an isClearable prop that provides a clear "X" icon. (example below)

Thanks for the considerations and great work!
