Persistent global restart required notification

What is the feature you'd like to have?
A bunch of things in Binary Ninja require you to restart for it to take effect (updates, settings, plugins...), but currently updates are the only one in that category that gets a persistent notification for the user. I'd like for other "Restart Required" actions to be able to trigger a persistent global restart required notification as well.

Is your feature request related to a problem?
Related to #5614, specifically the note that the temporal notification is easy to miss.

Are any alternative solutions acceptable?
A single icon with hover text that lists all the reasons a restart is required or multiple icons for each reason could be nice. This could replace the current update button, but I got some feedback that multiple icons could be preferred.

Start by reviewing the existing update notification and the discussion in #5614. Decide whether restart reasons should appear through one combined icon or multiple icons, then define how non-update restart-required actions remain visible; done means those actions produce a persistent global restart notification.
