LibWebView+WebContent: Expose the Accessibility Tree to Other Processes

Browse source 
This patch also stubs out notify_server_did_get_accessiblity_tree in
ladybird since ViewImplementation now has it. However, this feature
is still immature, so just stubbing out in ladybird for now. Once we
have more robust support in Serenity (namely ARIA properties/state
and accessible names and descriptions) we can port this
functionality over.
