[AppKit] Add missing Accessibility protocols.

This commit adds a few protocols that were missing. It is interesting to
mention that there are two of the protocols that are decorated with
NS_PROTOCOL_REQUIRES_EXPLICIT_IMPLEMENTATION, as per Apple documentation
this means that:

'Unlike normal protocols, when you adopt one of the role-specific protocols,
 Xcode may ask you to reimplement methods that have already been implemented
 by one of your ancestors.

 In order to ensure that your control returns accurate and useful information,
 some methods are tagged with the NS_PROTOCOL_REQUIRES_EXPLICIT_IMPLEMENTATION
 attribute. For these methods, you need to override your superclass’s
 implementation with your own.
'

In this case, we need to add the methods from all the parent classes and
set them to be [Abstract] since they are required. Not all methods have
to be added ONLY the required ones.

fixes: #7079
