feels like this might better live in AccessibilityObject. There's an existing

bool AccessibilityObject::isARIAControl(AccessibilityRole ariaRole) that might be appropriate

not sure we want to tap ListBox

do we want to tap text areas and text fields?

this might be better written as a switch statement

ariaRoleToWebCoreRole should handle null and empty strings. you can probably remove this if
