Use NativeDebuggerSessionObserver in LogBox (facebook#45578)

Summary:
Pull Request resolved: facebook#45578

# Changelog: [Internal]

Use previously introduced native module for managing the presence of warning notifications in LogBox:
- Don't display warnings and Fusebox migration message if there is an active debugging session
- If the session has just been started, clear warnings to hide Fusebox migration message
- If there is no active debugging session (even if there were some at some point of Host lifetime), display Fusebox migration message

See demo in test plan.
