[ATK] Expose aria-haspopup and aria-sort without the 'aria-' prefix
https://bugs.webkit.org/show_bug.cgi?id=121495

Reviewed by Chris Fleizach.

Source/WebCore:

Removed the 'aria-' prefix from the exposed ATK object attributes
for WAI-ARIA attributes 'aria-haspopup' and 'aria-sort'.

* accessibility/atk/WebKitAccessibleWrapperAtk.cpp:
(webkitAccessibleGetAttributes): Removed the prefix.

Tools:

Adapted DRT and WKTR to deal with the new names for the ATK object
attributes being exposed for 'aria-haspopup' and 'aria-sort'.

* DumpRenderTree/atk/AccessibilityUIElementAtk.cpp:
(coreAttributeToAtkAttribute): Updated translation between ATK and DRT.
(AccessibilityUIElement::stringAttributeValue): Ditto.
(AccessibilityUIElement::hasPopup): Ditto.
* WebKitTestRunner/InjectedBundle/atk/AccessibilityUIElementAtk.cpp:
(WTR::coreAttributeToAtkAttribute): Updated translation between ATK and WKTR.
(WTR::AccessibilityUIElement::stringAttributeValue): Ditto.
(WTR::AccessibilityUIElement::hasPopup): Ditto.

LayoutTests:

Rebaseline test expectations that were displaying the 'aria-sort'
attributes incorrectly, when they shouldn't due to that ARIA
attribute not being explicitly used in the HTML.
