macos: trigger fullscreenDidChange on any fullscreen event

Fixes #2840
Related to #2842

This builds on #2842 by missing a key situation: when native fullscreen
is toggled using the menu bar items it doesn't go through our
`FullscreenStyle` machinery so we don't trigger fullscreen change
events.

This commit makes it so that our FullscreenStyle always listens for
native fullscreen change (even in non-native modes) to fire a fullscreen
did change event. This way we can always rely on the event to be fired
when fullscreen changes no matter what.
