RFR: 8377745: VoiceOver Identifies Hyperlink as Text [v2]

[Jeremy Wood]

> If we use `new AccessibleRole("AXLink") {}`, then VoiceOver reads this more like other native apps.
> 
> There isn't a similar precedent in CAccessibility for creating custom AccessibleRoles, so I won't mind if this PR is declined. (But I don't know off the top of my head where else to inject code to get the desired result...)

Jeremy Wood has updated the pull request incrementally with two additional commits since the last revision:

 - 8377745: creating new LinkAccessibility
   
   This helps convert from AccessibleRole.HYPERLINK to the new LinkAccessibility.
   
   The new LinkAccessible still references `CommonTextAccessibility<NSAccessibilityStaticText>`.
   
   This (both the subject matter and the programming language) is outside of my area of expertise, but the unit test passes.
   
   This is based on this feedback:
