[iOS] Support text selection and interaction using UIAsyncTextInterac…

Reviewed by Aditya Keerthi.

Implement the remaining set of methods on `WKTextInteractionWrapper`, in the case where the wrapper
is backed by `UIAsyncTextInteraction`. This enables basic text interactions (such as multi-tap,
range adjustment, and tap-and-half gestures), as well as context menu interactions for links and
images in the page, and finally the ability to temporarily suppress the text selection when we're
either inside of a hidden editable container, or while the selection is inside of a scrolling
overflow container.

Depends on the changes in rdar://117831560 as well.
