Add "Dismiss x" button to the "Disconnected from dev server" Fast Refresh notifier message (#54445)
Summary: Changelog: DevServer fast refresh banners now have a dismiss button but still tap anywhere to dismiss. 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. Differential Revision: D86420230
