  AX: Soft-link UIAccessibility constants rather than duplicating them in iOS AX
https://bugs.webkit.org/show_bug.cgi?id=263487
rdar://problem/117287269

Reviewed by Chris Fleizach.

Duplicating them can cause conflicts when we try to link the framework they're defined in.
Linking the symbols also prevents bugs in case the NSString* representation changes in the
framework without also changing our duplicated version.

This patch also removes UIAccessibilityTokenHeadingLevel and its setting function,
attributeStringSetHeadingLevel, entirely, as UIAccessibilityTokenHeadingLevel is not used by any AT or framework.
