[deprecation] ExitFullScreenButton migration

[clintandrewhall]

See: #125750

The ExitFullScreenButton in kibana_react has been deprecated. There are currently two active plugins where this component is used, and two questions about consistency in Kibana. This issue will track migration in order to facilitate deleting the old button and removing page bundle bloat (#114990)

Awaiting Migration

Once these plugins move to the new component, the issue raised in #114990 will be addressed for the deprecated component.

Why doesn't Canvas use an Exit Full Screen button?

I don't recall if it was clear decision not to include it, but I suspect it would be of annoyance when you're presenting in full screen mode given that it is always visible/overlaid. Perhaps if it only showed on hover or focus would negate that.

To be honest this is a general problem with it that affects dashboards as well. We should pursue looking into other options for placement for all usages, but implement the changes in the new Shared UX component.

@ryankeairns @cchaos We could go the route that if the mouse doesn't move, the button fades away and returns if the mouse moves? We've seen that pattern in other apps.

But I agree: we should code that into this component so all benefit.

FWIW, Google Slides shows this bit of UI only when you hover/focus on the bottom left portion of the screen and it fades as you move out.

Bonus: They also show a brief tip upon entering full screen that you can press ESC to exit.

@ryankeairns Nice. All things we should consider here, and stuff we can bake into this component.

I think this was done
