AX: a base appearance multi-select dropdown box is exposed as a list box

Reviewed by Tyler Wilcock.
AccessibilityRenderObject::determineAccessibilityRole() gives a select that
uses a menu list the
pop-up button role, unless it is a multi-select, and any other select the list
box role. A native
dropdown box is an AccessibilityMenuList, which has its own role, so only a
select with a base
appearance picker gets here. A multi-select dropdown box with a base appearance
picker therefore
became a list box, although it renders as a button with a picker. Without
HTMLEnhancedSelectMultipleDropdownBoxEnabled it does not use a menu list either.
Base the role on the box type of the select instead, as HTML-AAM maps a select
rendered as a
drop-down box to combobox and one rendered as a list box to listbox.
