        Define new roles in WebCore and map them to ATK accordingly.

        Test: platform/gtk/accessibility/aria-roles-unignored.html

        * accessibility/AccessibilityObject.h: Added new roles to
        represent paragraphs, labels, forms and div sections.
        * accessibility/AccessibilityRenderObject.cpp:
        (WebCore::AccessibilityRenderObject::determineAccessibilityRole):
        Return ParagraphRole, LabelRole, FormRole and DivRole when needed
        for the GTK platform only.
        * accessibility/gtk/AccessibilityObjectAtk.cpp:
        (WebCore::AccessibilityObject::allowsTextRanges): Consider the new
        roles now that those kind of nodes won't return true to isGroup().
        * accessibility/gtk/AccessibilityObjectWrapperAtk.cpp:
        (atkRole): Map new WebCore roles to ATK Roles.
        (webkit_accessible_get_role): Remove code to define roles for
        paragraphs, labels, forms and divs based on node's tag name.

        Update mappings for the Mac platform.

        * accessibility/mac/AccessibilityObjectWrapper.mm:
        (createAccessibilityRoleMap): Add explicit mappings from the new
        roles introduced to NSAccessibilityGroupRole.
