Add "Dismiss x" button to the "Disconnected from dev server" Fast Refresh notifier message (#54445)

Summary:

Add a "Dismiss x" button to the fast refresh disconnected banners in the react native DevLoadingView to act as a visual cue for the current click anywhere to dismiss gesture.

Add new parameter to the devLoadingView turbo module to determine whether a message has this dismiss button.
