macOS: fix separator actions not showing in menus

Browse Source 
Amends a3f3af8a8fb8f8b09d1685df5ab836244f850a62, which resulted in the
last visible separator always getting hidden.

Don't abuse QCocoaMenuItem::visible property to store whether the native
NSMenuItem is shown, only store whether it should be shown.

Rename the local variables to simplify the logic.

Fixes: QTBUG-94802
