Support HTML5 <datalist> element
The datalist uses Chromium's autofill component to fetch and filter predefined options in the list and autocomplete the field with the selected option. Autofill component is added to build and bound to WebEngine. All the unnecessary autofill features for datalist are supposed to be disabled: payment/credit card support, password manager, save profile data, store suggestions in database etc. Custom popups for the dropdown are implemented for Widget and Quick. Scrolling in dropdown is not implemented in this change. Fixes: QTBUG-54433 Pick-to: 6.4 Change-Id: I155d02d6dbc9d88fbca4bc5f55b76c19d0ba7a9d Reviewed-by: Allan Sandfeld Jensen <allan.jensen@qt.io>
