Bring back the ariaOwneeID prop. (#1883)

Summary:
**Summary**

Reverts 7f0cab2 to bring back the `ariaOwneeID` prop. The ARIA property `aria-owns` is required for the combobox ARIA widget, in both ARIA 1.0 and 1.1. Some plugins, for example the Mentions and Emoji plugins, still pass an `ariaOwneeID` prop which at the moment doesn't do anything. Also, without `aria-owns`, some browser / screen reader combinations don't read out the suggestions at all. For more details please refer to the related issue #1736.

Fixes #1736.
