UiDropdownMenu class

Dropdown menu surface + trigger.

The trigger widget is made tappable; on tap (and optionally long press) an overlay with the items renders below. When openOnLongPress is true, the initiating pointer can drag across items and release to select one. Keyboard users can move up/down through the rows and activate them with Enter/Space.
